9403810c02 toolchain: Select USE_SSTRIP with external musl toolchain
When we use the internal toolchain USE_SSTRIP will be selected by
default for musl libc and USE_STRIP when glibc is used. Do the same when
an external toolchain is used. USE_GLIBC will also be set for external
toolchain builds based on the EXTERNAL_TOOLCHAIN_LIBC_USE_GLIBC setting.

31a6605de0 mac80211: rt2x00: experimental improvements for MT7620 wifi
Serge Vasilugin reports:

To improve mt7620 built-in wifi performance some changes:
1. Correct BW20/BW40 switching (see comments with mark (1))
2. Correct TX_SW_CFG1 MAC reg from v3 of vendor driver see
	https://gitlab.com/dm38/padavan-ng/-/blob/master/trunk/proprietary/rt_wifi/rtpci/3.0.X.X/mt76x2/chips/rt6352.c#L531
3. Set bbp66 for all chains.
4. US_CYC_CNT init based on Programming guide, default value was 33 (pci),
   set chipset bus clock with fallback to cpu clock/3.
5. Don't overwrite default values for mt7620.
6. Correct some typos.
7. Add support for external LNA:
    a) RF and BBP regs never be corrected for this mode
    b) eLNA is driven the same way as ePA with mt7620's pin PA
	but vendor driver explicitly pin PA to gpio mode (for forrect calibration?)
	so I'm not sure that request for pa_pin in dts-file will be enough

First 5 changes (really 2) improve performance for boards w/o eLNA/ePA.
Changes 7 add support for eLNA

Configuration w/o eLAN/ePA and with eLNA show results
tx/rx (from router point of view) for each stream:
 35-40/30-35 Mbps for HT20
 65-70/60-65 Mbps for HT40

Yes. Max results for 2T2R client is 140-145/135-140
with peaks 160/150, It correspond to mediatek driver results.
Boards with ePA untested.

20581ee8b5 ath79: add support for TP-Link Deco S4
Add support for TP-Link Deco S4 wifi router

The label refers to the device as S4R and the TP-Link firmware
site calls it the Deco S4 v2. (There does not appear to be a v1)

Hardware (and FCC id) are identical to the Deco M4R v2 but the
flash layout is ordered differently and the OEM firmware encrypts
some config parameters (including the label mac address) in flash

In order to set the encrypted mac address, the wlan's caldata
node is removed from the DTS so the mac can be decrypted with
the help of the uencrypt tool and patched into the wlan fw
via hotplug

Specifications:
SoC: QCA9563-AL3A
RAM: Zentel A3R1GE40JBF
Wireless 2.4GHz: QCA9563-AL3A (main SoC)
Wireless 5GHz: QCA9886
Ethernet Switch: QCA8337N-AL3C
Flash: 16 MB SPI NOR

UART serial access (115200N1) on board via solder pads:
RX = TP1 pad
TX = TP2 pad
GND = C201 (pad nearest board edge)

The device's bootloader and web gui will only accept images that
were signed using TP-Link's RSA key, however a memory safety bug
in the bootloader can be leveraged to install openwrt without
accessing the serial console. See developer forum S4 support page
for link to a "firmware" file that starts a tftp client, or you
may generate one on your own like this:

5df1b33298 ath79: add support for Senao Watchguard AP100
FCC ID: U2M-CAP2100AG

WatchGuard AP100 is an indoor wireless access point with
1 Gb ethernet port, dual-band but single-radio wireless,
internal antenna plates, and 802.3at PoE+

this board is a Senao device:
the hardware is equivalent to EnGenius EAP300 v2
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails

**Specification:**

  - AR9344 SOC          MIPS 74kc, 2.4 GHz AND 5 GHz WMAC, 2x2
  - AR8035-A EPHY       RGMII GbE with PoE+ IN
  - 25 MHz clock
  - 16 MB FLASH         mx25l12805d
  - 2x 64 MB RAM
  - UART console        J11, populated
  - GPIO watchdog       GPIO 16, 20 sec toggle
  - 2 antennas          5 dBi, internal omni-directional plates
  - 5 LEDs              power, eth0 link/data, 2G, 5G
  - 1 button            reset

**MAC addresses:**

  Label has no MAC
  Only one Vendor MAC address in flash at art 0x0

  eth0 ---- *:e5 art 0x0 -2
  phy0 ---- *:e5 art 0x0 -2

**Installation:**

  Method 1: OEM webpage

    use OEM webpage for firmware upgrade to upload factory.bin

  Method 2: root shell

    It may be necessary to use a Watchguard router to flash the image to the AP
    and / or to downgrade the software on the AP to access SSH
    For some Watchguard devices, serial console over UART is disabled.

  NOTE: DHCP is not enabled by default after flashing

**TFTP recovery:**

  reset button has no function at boot time
  only possible with modified uboot environment,
  (see commit message for Watchguard AP300)

**Return to OEM:**

  user should make backup of MTD partitions
  and write the backups back to mtd devices
  in order to revert to OEM reliably

  It may be possible to use sysupgrade
  with an OEM image as well...
  (not tested)

**OEM upgrade info:**

  The OEM upgrade script is at /etc/fwupgrade.sh

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

**Note on eth0 PLL-data:**

  The default Ethernet Configuration register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For AR934x series, the PLL registers for eth0
  can be see in the DTSI as 0x2c.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x1805002c 1`.

  The clock delay required for RGMII can be applied
  at the PHY side, using the at803x driver `phy-mode`.
  Therefore the PLL registers for GMAC0
  do not need the bits for delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

**Note on WatchGuard Magic string:**

  The OEM upgrade script is a modified version of
  the generic Senao sysupgrade script
  which is used on EnGenius devices.

  On WatchGuard boards produced by Senao,
  images are verified using a md5sum checksum of
  the upgrade image concatenated with a magic string.
  this checksum is then appended to the end of the final image.

  This variable does not apply to all the senao devices
  so set to null string as default

146aaeafb7 ath79: add support for Senao WatchGuard AP300
FCC ID: Q6G-AP300

WatchGuard AP300 is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

this board is a Senao device:
the hardware is equivalent to EnGenius EAP1750
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails

**Specification:**

  - QCA9558 SOC		MIPS 74kc, 2.4 GHz WMAC, 3x3
  - QCA9880 WLAN	PCI card 168c:003c, 5 GHz, 3x3, 26dBm

  - 40 MHz clock
  - 32 MB FLASH		S25FL512S
  - 2x 64 MB RAM	NT5TU32M16
  - UART console	J10, populated
  - GPIO watchdog	GPIO 16, 20 sec toggle
  - 6 antennas		5 dBi, internal omni-directional plates
  - 5 LEDs		power, eth0 link/data, 2G, 5G
  - 1 button		reset

**MAC addresses:**

  MAC address labeled as ETH
  Only one Vendor MAC address in flash at art 0x0

  eth0 ETH  *:3c art 0x0
  phy1 ---- *:3d ---
  phy0 ---- *:3e ---

**Serial console access:**

  For this board, its not certain whether UART is possible
  it is likely that software is blocking console access

  the RX line on the board for UART is shorted to ground by resistor R176
  the resistors R175 and R176 are next to the UART RX pin at J10

  however console output is garbage even after this fix

**Installation:**

  Method 1: OEM webpage

    use OEM webpage for firmware upgrade to upload factory.bin

  Method 2: root shell access

    downgrade XTM firewall to v2.0.0.1
    downgrade AP300 firmware: v1.0.1
    remove / unpair AP from controller
    perform factory reset with reset button
    connect ethernet to a computer
    login to OEM webpage with default address / pass: wgwap
    enable SSHD in OEM webpage settings
    access root shell with SSH as user 'root'
    modify uboot environment to automatically try TFTP at boot time
    (see command below)

    rename initramfs-kernel.bin to test.bin
    load test.bin over TFTP (see TFTP recovery)
    (optionally backup all mtdblocks to have flash backup)
    perform a sysupgrade with sysupgrade.bin

  NOTE: DHCP is not enabled by default after flashing

**TFTP recovery:**

  server ip: 192.168.1.101

  reset button seems to do nothing at boot time...
  only possible with modified uboot environment,
  running this command in the root shell:

  fw_setenv bootcmd 'if ping 192.168.1.101; then tftp 0x82000000 test.bin && bootm 0x82000000; else bootm 0x9f0a0000; fi'

  and verify that it is correct with

  fw_printenv

  then, before boot, the device will attempt TFTP from 192.168.1.101
  looking for file 'test.bin'

  to return uboot environment to normal:

  fw_setenv bootcmd 'bootm 0x9f0a0000'

**Return to OEM:**

  user should make backup of MTD partitions
  and write the backups back to mtd devices
  in order to revert to OEM
  (see installation method 2)

  It may be possible to use sysupgrade
  with an OEM image as well...
  (not tested)

  The default Ethernet Configuration register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied
  at the PHY side, using the at803x driver `phy-mode`.
  Therefore the PLL registers for GMAC0
  do not need the bits for delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

**Note on WatchGuard Magic string:**

  The OEM upgrade script is a modified version of
  the generic Senao sysupgrade script
  which is used on EnGenius devices.

  On WatchGuard boards produced by Senao,
  images are verified using a md5sum checksum of
  the upgrade image concatenated with a magic string.
  this checksum is then appended to the end of the final image.

  This variable does not apply to all the senao devices
  so set to null string as default

The RGB LED of the UniFi 6 LR v1 doesn't work when using the Openwrt-

controller while our U-Boot doesn't care.
Add reset-gpio so the ledbar driver in Linux will always reset the

0be1b78856 ipq40xx: cellc_rtl30vw: fix imagebuilder generation
The image build process was modifying the generated IMAGE_KERNEL to
append rootfs information (crc). This caused:
 - sysupgrade & factory images to contain 2 times the root.squashfs
   information due to both modifying the same IMAGE_KERNEL.
 - the generated imagebuilder to contain an erroneous IMAGE_KERNEL that
   contained references to an unexisting root.squashfs (the one from
   previous cause). The RTL30VW wasn't therefore able to boot the
   generated images as they contained checksums from non existing rootfs.

This commit makes sure to use a temporary IMAGE_KERNEL to append the
rootfs information for both factory and sysupgrade images.

f1d112ee5a ath79: support Ruckus ZoneFlex 7321
Ruckus ZoneFlex 7321 is a dual-band, single radio 802.11n 2x2 MIMO enterprise
access point. It is very similar to its bigger brother, ZoneFlex 7372.

Hardware highligts:
- CPU: Atheros AR9342 SoC at 533 MHz
- RAM: 64MB DDR2
- Flash: 32MB SPI-NOR
- Wi-Fi: AR9342 built-in dual-band 2x2 MIMO radio
- Ethernet: single Gigabit Ethernet port through AR8035 gigabit PHY
- PoE: input through Gigabit port
- Standalone 12V/1A power input
- USB: optional single USB 2.0 host port on the 7321-U variant.

Serial console: 115200-8-N-1 on internal H1 header.
Pinout:

   |1|x3|4|5|
   ----------

Pin 1 is near the "H1" marking.
1 - RX
x - no pin
3 - VCC (3.3V)
4 - GND
5 - TX

JTAG: Connector H5, unpopulated, similar to MIPS eJTAG, standard,
but without the key in pin 12 and not every pin routed:

------- H5
|1 |2 |
-------
|3 |4 |

3 - TDI
5 - TDO
7 - TMS
9 - TCK
2,4,6,8,10 - GND
14 - Vref
1,11,12,13 - Not connected

Installation:
There are two methods of installation:
- Using serial console [1] - requires some disassembly, 3.3V USB-Serial
  adapter, TFTP server,  and removing a single T10 screw,
  but with much less manual steps, and is generally recommended, being
  safer.
- Using stock firmware root shell exploit, SSH and TFTP [2]. Does not
  work on some rare versions of stock firmware. A more involved, and
  requires installing `mkenvimage` from u-boot-tools package if you
  choose to rebuild your own environment, but can be used without
  disassembly or removal from installation point, if you have the
  credentials.
  If for some reason, size of your sysupgrade image exceeds 13312kB,
  proceed with method [1]. For official images this is not likely to
  happen ever.

[1] Using serial console:
0. Connect serial console to H1 header. Ensure the serial converter
   does not back-power the board, otherwise it will fail to boot.

1. Power-on the board. Then quickly connect serial converter to PC and
   hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
   you'll enter U-boot shell. Then skip to point 3.
   Connection parameters are 115200-8-N-1.

2. Allow the board to boot.  Press the reset button, so the board
   reboots into U-boot again and go back to point 1.

3. Set the "bootcmd" variable to disable the dual-boot feature of the
   system and ensure that uImage is loaded. This is critical step, and
   needs to be done only on initial installation.

   > setenv bootcmd "bootm 0x9f040000"
   > saveenv

4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:

   > setenv serverip 192.168.1.2
   > setenv ipaddr 192.168.1.1
   > tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7321-initramfs-kernel.bin
   > bootm 0x81000000

5. Optional, but highly recommended: back up contents of "firmware" partition:

   $ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7321_fw1_backup.bin
   $ ssh root@192.168.1.1 cat /dev/mtd5 > ruckus_zf7321_fw2_backup.bin

6. Copy over sysupgrade image, and perform actual installation. OpenWrt
   shall boot from flash afterwards:

   $ ssh root@192.168.1.1
   # sysupgrade -n openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin

[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
   it boots, hold the reset button near Ethernet connectors for 5
   seconds.

1. Connect the device to the network. It will acquire address over DHCP,
   so either find its address using list of DHCP leases by looking for
   label MAC address, or try finding it by scanning for SSH port:

   $ nmap 10.42.0.0/24 -p22

   From now on, we assume your computer has address 10.42.0.1 and the device
   has address 10.42.0.254.

2. Set up a TFTP server on your computer. We assume that TFTP server
   root is at /srv/tftp.

3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
   frmware is pretty ancient and requires enabling HMAC-MD5.

   $ ssh 10.42.0.254 \
   -o UserKnownHostsFile=/dev/null \
   -o StrictHostKeyCheking=no \
   -o MACs=hmac-md5

   Login. User is "super", password is "sp-admin".
   Now execute a hidden command:

   Ruckus

   It is case-sensitive. Copy and paste the following string,
   including quotes. There will be no output on the console for that.

   ";/bin/sh;"

   Hit "enter". The AP will respond with:

   grrrr
   OK

   Now execute another hidden command:

   !v54!

   At "What's your chow?" prompt just hit "enter".
   Congratulations, you should now be dropped to Busybox shell with root
   permissions.

4. Optional, but highly recommended: backup the flash contents before
   installation. At your PC ensure the device can write the firmware
   over TFTP:

   $ sudo touch /srv/tftp/ruckus_zf7321_firmware{1,2}.bin
   $ sudo chmod 666 /srv/tftp/ruckus_zf7321_firmware{1,2}.bin

   Locate partitions for primary and secondary firmware image.
   NEVER blindly copy over MTD nodes, because MTD indices change
   depending on the currently active firmware, and all partitions are
   writable!

   # grep rcks_wlan /proc/mtd

   Copy over both images using TFTP, this will be useful in case you'd
   like to return to stock FW in future. Make sure to backup both, as
   OpenWrt uses bot firmwre partitions for storage!

   # tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7321_firmware1.bin -p 10.42.0.1
   # tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7321_firmware2.bin -p 10.42.0.1

   When the command finishes, copy over the dump to a safe place for
   storage.

   $ cp /srv/tftp/ruckus_zf7321_firmware{1,2}.bin ~/

5. Ensure the system is running from the BACKUP image, i.e. from
   rcks_wlan.bkup partition or "image 2". Otherwise the installation
   WILL fail, and you will need to access mtd0 device to write image
   which risks overwriting the bootloader, and so is not covered here
   and not supported.

   Switching to backup firmware can be achieved by executing a few
   consecutive reboots of the device, or by updating the stock firmware. The
   system will boot from the image it was not running from previously.
   Stock firmware available to update was conveniently dumped in point 4 :-)

6. Prepare U-boot environment image.
   Install u-boot-tools package. Alternatively, if you build your own
   images, OpenWrt provides mkenvimage in host staging directory as well.
   It is recommended to extract environment from the device, and modify
   it, rather then relying on defaults:

   $ sudo touch /srv/tftp/u-boot-env.bin
   $ sudo chmod 666 /srv/tftp/u-boot-env.bin

   On the device, find the MTD partition on which environment resides.
   Beware, it may change depending on currently active firmware image!

   # grep u-boot-env /proc/mtd

   Now, copy over the partition

   # tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1

   Store the stock environment in a safe place:

   $ cp /srv/tftp/u-boot-env.bin ~/

   Extract the values from the dump:

   $ strings u-boot-env.bin | tee u-boot-env.txt

   Now clean up the debris at the end of output, you should end up with
   each variable defined once. After that, set the bootcmd variable like
   this:

   bootcmd=bootm 0x9f040000

   You should end up with something like this:

bootcmd=bootm 0x9f040000
bootargs=console=ttyS0,115200 rootfstype=squashfs init=/sbin/init
baudrate=115200
ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee
mtdparts=mtdparts=ar7100-nor0:256k(u-boot),13312k(rcks_wlan.main),2048k(datafs),256k(u-boot-env),512k(Board Data),13312k(rcks_wlan.bkup)
mtdids=nor0=ar7100-nor0
bootdelay=2
ethact=eth0
filesize=78a000
fileaddr=81000000
partition=nor0,0
mtddevnum=0
mtddevname=u-boot
ipaddr=10.0.0.1
serverip=10.0.0.5
stdin=serial
stdout=serial
stderr=serial

   These are the defaults, you can use most likely just this as input to
   mkenvimage.

   Now, create environment image and copy it over to TFTP root:

   $ mkenvimage -s 0x40000 -b -o u-boot-env.bin u-boot-env.txt
   $ sudo cp u-boot-env.bin /srv/tftp

   This is the same image, gzipped and base64-encoded:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
   TFTP root:

   $ sudo cp openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin /srv/tftp

   Now load both to the device over TFTP:

   # tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
   # tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin -g 10.42.0.1

   Vverify checksums of both images to ensure the transfer over TFTP
   was completed:

   # sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin

   And compare it against source images:

   $ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin

   Locate MTD partition of the primary image:

   # grep rcks_wlan.main /proc/mtd

   Now, write the images in place. Write U-boot environment last, so
   unit still can boot from backup image, should power failure occur during
   this. Replace MTD placeholders with real MTD nodes:

   # flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
   # flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>

   Finally, reboot the device. The device should directly boot into
   OpenWrt. Look for the characteristic power LED blinking pattern.

   # reboot -f

   After unit boots, it should be available at the usual 192.168.1.1/24.

Return to factory firmware:

1. Boot into OpenWrt initramfs as for initial installation. To do that
   without disassembly, you can write an initramfs image to the device
   using 'sysupgrade -F' first.
2. Unset the "bootcmd" variable:
   fw_setenv bootcmd ""
3. Write factory images downloaded from manufacturer website into
   fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
   before installation:
   mtd write ruckus_zf7321_fw1_backup.bin /dev/mtd1
   mtd write ruckus_zf7321_fw2_backup.bin /dev/mtd5
4. Reboot the system, it should load into factory firmware again.

Quirks and known issues:
- Flash layout is changed from the factory, to use both firmware image
  partitions for storage using mtd-concat, and uImage format is used to
  actually boot the system, which rules out the dual-boot capability.
- The 5GHz radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
  OpenWrt by choice.
  It is controlled by data in the top 64kB of RAM which is unmapped,
  to avoid   the interference in the boot process and accidental
  switch to the inactive image, although boot script presence in
  form of "bootcmd" variable should prevent this entirely.
- U-boot disables JTAG when starting. To re-enable it, you need to
  execute the following command before booting:
  mw.l 1804006c 40
  And also you need to disable the reset button in device tree if you
  intend to debug Linux, because reset button on GPIO0 shares the TCK
  pin.
- On some versions of stock firmware, it is possible to obtain root shell,
  however not much is available in terms of debugging facitilies.
  1. Login to the rkscli
  2. Execute hidden command "Ruckus"
  3. Copy and paste ";/bin/sh;" including quotes. This is required only
     once, the payload will be stored in writable filesystem.
  4. Execute hidden command "!v54!". Press Enter leaving empty reply for
     "What's your chow?" prompt.
  5. Busybox shell shall open.

- Wi-Fi 2.4GHz: AR9344 built-in 2x2 MIMO radio
- Wi-Fi 5Ghz: AR9582 2x2 MIMO radio (Only in ZF7372)
- Antennas:
  - Separate internal active antennas with beamforming support on both
    bands with 7 elements per band, each controlled by 74LV164 GPIO
    expanders, attached to GPIOs of each radio.
  - Two dual-band external RP-SMA antenna connections on "7372-E"
    variant.
- Ethernet 1: single Gigabit Ethernet port through AR8035 gigabit PHY
- Ethernet 2: single Fast Ethernet port through AR9344 built-in switch
- PoE: input through Gigabit port
- Standalone 12V/1A power input
- USB: optional single USB 2.0 host port on "-U" variants.

The same image should support:
- ZoneFlex 7372E (variant with external antennas, without beamforming
  capability)
- ZoneFlex 7352 (single-band, 2.4GHz-only variant).

Installation:
There are two methods of installation:
- Using serial console [1] - requires some disassembly, 3.3V USB-Serial
  adapter, TFTP server,  and removing a single T10 screw,
  but with much less manual steps, and is generally recommended, being
  safer.
- Using stock firmware root shell exploit, SSH and TFTP [2]. Does not
  work on some rare versions of stock firmware. A more involved, and
  requires installing `mkenvimage` from u-boot-tools package if you
  choose to rebuild your own environment, but can be used without
  disassembly or removal from installation point, if you have the
  credentials.
  If for some reason, size of your sysupgrade image exceeds 13312kB,
  proceed with method [1]. For official images this is not likely to
  happen ever.

[1] Using serial console:
0. Connect serial console to H1 header. Ensure the serial converter
   does not back-power the board, otherwise it will fail to boot.

1. Power-on the board. Then quickly connect serial converter to PC and
   hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
   you'll enter U-boot shell. Then skip to point 3.
   Connection parameters are 115200-8-N-1.

2. Allow the board to boot.  Press the reset button, so the board
   reboots into U-boot again and go back to point 1.

3. Set the "bootcmd" variable to disable the dual-boot feature of the
   system and ensure that uImage is loaded. This is critical step, and
   needs to be done only on initial installation.

   > setenv bootcmd "bootm 0x9f040000"
   > saveenv

4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:

   > setenv serverip 192.168.1.2
   > setenv ipaddr 192.168.1.1
   > tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7372-initramfs-kernel.bin
   > bootm 0x81000000

5. Optional, but highly recommended: back up contents of "firmware" partition:

   $ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7372_fw1_backup.bin
   $ ssh root@192.168.1.1 cat /dev/mtd5 > ruckus_zf7372_fw2_backup.bin

6. Copy over sysupgrade image, and perform actual installation. OpenWrt
   shall boot from flash afterwards:

   $ ssh root@192.168.1.1
   # sysupgrade -n openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin

[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
   it boots, hold the reset button near Ethernet connectors for 5
   seconds.

1. Connect the device to the network. It will acquire address over DHCP,
   so either find its address using list of DHCP leases by looking for
   label MAC address, or try finding it by scanning for SSH port:

   $ nmap 10.42.0.0/24 -p22

   From now on, we assume your computer has address 10.42.0.1 and the device
   has address 10.42.0.254.

2. Set up a TFTP server on your computer. We assume that TFTP server
   root is at /srv/tftp.

3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
   frmware is pretty ancient and requires enabling HMAC-MD5.

   $ ssh 10.42.0.254 \
   -o UserKnownHostsFile=/dev/null \
   -o StrictHostKeyCheking=no \
   -o MACs=hmac-md5

   Login. User is "super", password is "sp-admin".
   Now execute a hidden command:

   Ruckus

   It is case-sensitive. Copy and paste the following string,
   including quotes. There will be no output on the console for that.

   ";/bin/sh;"

   Hit "enter". The AP will respond with:

   grrrr
   OK

   Now execute another hidden command:

   !v54!

   At "What's your chow?" prompt just hit "enter".
   Congratulations, you should now be dropped to Busybox shell with root
   permissions.

4. Optional, but highly recommended: backup the flash contents before
   installation. At your PC ensure the device can write the firmware
   over TFTP:

   $ sudo touch /srv/tftp/ruckus_zf7372_firmware{1,2}.bin
   $ sudo chmod 666 /srv/tftp/ruckus_zf7372_firmware{1,2}.bin

   Locate partitions for primary and secondary firmware image.
   NEVER blindly copy over MTD nodes, because MTD indices change
   depending on the currently active firmware, and all partitions are
   writable!

   # grep rcks_wlan /proc/mtd

   Copy over both images using TFTP, this will be useful in case you'd
   like to return to stock FW in future. Make sure to backup both, as
   OpenWrt uses bot firmwre partitions for storage!

   # tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7372_firmware1.bin -p 10.42.0.1
   # tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7372_firmware2.bin -p 10.42.0.1

   When the command finishes, copy over the dump to a safe place for
   storage.

   $ cp /srv/tftp/ruckus_zf7372_firmware{1,2}.bin ~/

5. Ensure the system is running from the BACKUP image, i.e. from
   rcks_wlan.bkup partition or "image 2". Otherwise the installation
   WILL fail, and you will need to access mtd0 device to write image
   which risks overwriting the bootloader, and so is not covered here
   and not supported.

   Switching to backup firmware can be achieved by executing a few
   consecutive reboots of the device, or by updating the stock firmware. The
   system will boot from the image it was not running from previously.
   Stock firmware available to update was conveniently dumped in point 4 :-)

6. Prepare U-boot environment image.
   Install u-boot-tools package. Alternatively, if you build your own
   images, OpenWrt provides mkenvimage in host staging directory as well.
   It is recommended to extract environment from the device, and modify
   it, rather then relying on defaults:

   $ sudo touch /srv/tftp/u-boot-env.bin
   $ sudo chmod 666 /srv/tftp/u-boot-env.bin

   On the device, find the MTD partition on which environment resides.
   Beware, it may change depending on currently active firmware image!

   # grep u-boot-env /proc/mtd

   Now, copy over the partition

   # tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1

   Store the stock environment in a safe place:

   $ cp /srv/tftp/u-boot-env.bin ~/

   Extract the values from the dump:

   $ strings u-boot-env.bin | tee u-boot-env.txt

   Now clean up the debris at the end of output, you should end up with
   each variable defined once. After that, set the bootcmd variable like
   this:

   bootcmd=bootm 0x9f040000

   You should end up with something like this:

bootcmd=bootm 0x9f040000
bootargs=console=ttyS0,115200 rootfstype=squashfs init=/sbin/init
baudrate=115200
ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee
bootdelay=2
mtdids=nor0=ar7100-nor0
mtdparts=mtdparts=ar7100-nor0:256k(u-boot),13312k(rcks_wlan.main),2048k(datafs),256k(u-boot-env),512k(Board Data),13312k(rcks_wlan.bkup)
ethact=eth0
filesize=1000000
fileaddr=81000000
ipaddr=192.168.0.7
serverip=192.168.0.51
partition=nor0,0
mtddevnum=0
mtddevname=u-boot
stdin=serial
stdout=serial
stderr=serial

   These are the defaults, you can use most likely just this as input to
   mkenvimage.

   Now, create environment image and copy it over to TFTP root:

   $ mkenvimage -s 0x40000 -b -o u-boot-env.bin u-boot-env.txt
   $ sudo cp u-boot-env.bin /srv/tftp

   This is the same image, gzipped and base64-encoded:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
   TFTP root:

   $ sudo cp openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin /srv/tftp

   Now load both to the device over TFTP:

   # tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
   # tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin -g 10.42.0.1

   Verify checksums of both images to ensure the transfer over TFTP
   was completed:

   # sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin

   And compare it against source images:

   $ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin

   Locate MTD partition of the primary image:

   # grep rcks_wlan.main /proc/mtd

   Now, write the images in place. Write U-boot environment last, so
   unit still can boot from backup image, should power failure occur during
   this. Replace MTD placeholders with real MTD nodes:

   # flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
   # flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>

   Finally, reboot the device. The device should directly boot into
   OpenWrt. Look for the characteristic power LED blinking pattern.

   # reboot -f

   After unit boots, it should be available at the usual 192.168.1.1/24.

Return to factory firmware:

1. Boot into OpenWrt initramfs as for initial installation. To do that
   without disassembly, you can write an initramfs image to the device
   using 'sysupgrade -F' first.
2. Unset the "bootcmd" variable:
   fw_setenv bootcmd ""
3. Write factory images downloaded from manufacturer website into
   fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
   before installation:
   mtd write ruckus_zf7372_fw1_backup.bin /dev/mtd1
   mtd write ruckus_zf7372_fw2_backup.bin /dev/mtd5
4. Reboot the system, it should load into factory firmware again.

Quirks and known issues:
- This is first device in ath79 target to support link state reporting
  on FE port attached trough the built-in switch.
- Flash layout is changed from the factory, to use both firmware image
  partitions for storage using mtd-concat, and uImage format is used to
  actually boot the system, which rules out the dual-boot capability.
  The 5GHz radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
  OpenWrt by choice.
  It is controlled by data in the top 64kB of RAM which is unmapped,
  to avoid   the interference in the boot process and accidental
  switch to the inactive image, although boot script presence in
  form of "bootcmd" variable should prevent this entirely.
- U-boot disables JTAG when starting. To re-enable it, you need to
  execute the following command before booting:
  mw.l 1804006c 40
  And also you need to disable the reset button in device tree if you
  intend to debug Linux, because reset button on GPIO0 shares the TCK
  pin.
- On some versions of stock firmware, it is possible to obtain root shell,
  however not much is available in terms of debugging facitilies.
  1. Login to the rkscli
  2. Execute hidden command "Ruckus"
  3. Copy and paste ";/bin/sh;" including quotes. This is required only
     once, the payload will be stored in writable filesystem.
  4. Execute hidden command "!v54!". Press Enter leaving empty reply for
     "What's your chow?" prompt.
  5. Busybox shell shall open.
  Source: https://alephsecurity.com/vulns/aleph-2019014
- Stock firmware has beamforming functionality, known as BeamFlex,
  using active multi-segment antennas on both bands - controlled by
  RF analog switches, driven by a pair of 74LV164 shift registers.
  Shift registers used for each radio are connected to GPIO14 (clock)
  and GPIO15 of the respective chip.
  They are mapped as generic GPIOs in OpenWrt - in stock firmware,
  they were most likely handled directly by radio firmware,
  given the real-time nature of their control.
  Lack of this support in OpenWrt causes the antennas to behave as
  ordinary omnidirectional antennas, and does not affect throughput in
  normal conditions, but GPIOs are available to tinker with nonetheless.

62b72eafe4 ath79: mikrotik: use OpenWrt loader for initram image
Return to using the OpenWrt kernel loader to decompress and load kernel
initram image.

Continue to use the vmlinuz kernel for squashfs.

Mikrotik's bootloader RouterBOOT on some ath79 devices is
failing to boot the current initram, due to the size of the initram image.

On the ath79 wAP-ac:
a 5.7MiB initram image would fail to boot
After this change:
a 6.6MiB initram image successfully loads

This partially reverts commit e91344776b.

An alternative of using RouterBOOT's capability of loading an initrd ELF
section was investigated, but the OpenWrt kernel loader allows larger image.

WS-AP3825i, which has had repeated issues with the exact configuration
of u-boot, e.g. commit 1d06277407 ("mpc85xx: Fix output location of
padded dtb") (alongside other failures documented for example in this
post[^1] from the main AP3825i porting thread).

To assist with this, remove the `read-only` property from the u-boot
configuration partitions cfg1 and cfg2.

2f496c34b6 mpc85xx: add patch to fix gpio mpc8xxx
Backports patch, which is currently on review [1] for kernel 5.10 and
kernel 5.15, where it applies cleanly. This was tested on CZ.NIC Turris
1.1 router running OpenWrt 21.02.03 with kernel 5.15.

Before:

- In /var/log/messages:
```
[   16.392988] lm90 0-004c: cannot request IRQ 48
[   16.398280] lm90: probe of 0-004c failed with error -22
```

- Sensors does not work:
```
root@turris:~# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
```

After:

```
root@turris:/# sensors
sa56004-i2c-0-4c
Adapter: MPC adapter (i2c@3000)
temp1:        +44.0°C  (low  =  +0.0°C, high = +70.0°C)
                       (crit = +85.0°C, hyst = +75.0°C)
temp2:        +73.8°C  (low  =  +0.0°C, high = +70.0°C)  ALARM (HIGH)
                       (crit = +85.0°C, hyst = +75.0°C)
```
