a8e1e30543 uboot-bcm4908: include SoC in output files
This fixes problem of overwriting BCM4908 U-Boot and DTB files by
BCM4912 ones. That bug didn't allow booting BCM4908 devices.

6ae2f7ff47 bcm4908: build bootfs image per-SoC
In theory we could have just 1 bootfs image for all devices as each
device has its own entry in the "configurations" node. It doesn't work
well with default configuration though.

If something goes wrong U-Boot SPL can be interrupted (by pressing A) to
enter its minimalistic menu. It allows ignoring boardid. In such case
bootfs default configuration is used.

For above reason each SoC family (BCM4908, BCM4912) should have its own
bootfs built. It allows each of them to have working default
configuration.

a3e4949998 realtek: clear spurious GPIO interrupts
The interrupt controller in the internal GPIO peripheral will sometimes
generate spurious interrupts. If these are not properly acknowledged, the
system will be held busy until reboot. These spurious interrupts are identified
by the fact that there is no system IRQ number associated, since the interrupt
line was never allocated. Although most prevalent on RTL839x, RTL838x SoCs have
also displayed this behaviour.

a0b7fef0ff ramips: add support for ZyXEL NWA50AX / NWA55AXE
Hardware
--------
CPU:    Mediatek MT7621
RAM:    256M DDR3
FLASH:  128M NAND
ETH:    1x Gigabit Ethernet
WiFi:   Mediatek MT7915 (2.4/5GHz 802.11ax 2x2 DBDC)
BTN:    1x Reset (NWA50AX only)
LED:    1x Multi-Color (NWA50AX only)

UART Console
------------
NWA50AX:
Available below the rubber cover next to the ethernet port.
NWA55AXE:
Available on the board when disassembling the device.

Settings: 115200 8N1

Layout:

<12V> <LAN> GND-RX-TX-VCC

Logic-Level is 3V3. Don't connect VCC to your UART adapter!

Installation Web-UI
-------------------
Upload the Factory image using the devices Web-Interface.

As the device uses a dual-image partition layout, OpenWrt can only
installed on Slot A. This requires the current active image prior
flashing the device to be on Slot B.

If the currently installed image is started from Slot A, the device will
flash OpenWrt to Slot B. OpenWrt will panic upon first boot in this case
and the device will return to the ZyXEL firmware upon next boot.

If this happens, first install a ZyXEL firmware upgrade of any version
and install OpenWrt after that.

Installation TFTP
-----------------
This installation routine is especially useful in case
 * unknown device password (NWA55AXE lacks reset button)
 * bricked device

Attach to the UART console header of the device. Interrupt the boot
procedure by pressing Enter.

The bootloader has a reduced command-set available from CLI, but more
commands can be executed by abusing the atns command.

Boot a OpenWrt initramfs image available on a TFTP server at
192.168.1.66. Rename the image to owrt.bin

 $ atnf owrt.bin
 $ atna 192.168.1.88
 $ atns "192.168.1.66; tftpboot; bootm"

Upon booting, set the booted image to the correct slot:

 $ zyxel-bootconfig /dev/mtd10 get-status
 $ zyxel-bootconfig /dev/mtd10 set-image-status 0 valid
 $ zyxel-bootconfig /dev/mtd10 set-active-image 0

Copy the OpenWrt ramboot-factory image to the device using scp.
Write the factory image to NAND and reboot the device.

 $ mtd write ramboot-factory.bin firmware
 $ reboot

ipq40xx: add MikroTik wAP ac (RBwAPG-5HacD2HnD) support
The MikroTik wAP ac (RBwAPG-5HacD2HnD) is a dual-band dual-radio
802.11ac wireless access point with integrated antenna and two Ethernet
ports in a weatherproof enclosure. See
https://mikrotik.com/product/wap_ac for more information.

Important: this is the new ipq40xx-based wAP ac, not the older
ath79-based wAP ac (RBwAPG-5HacT2HnD), already supported in OpenWrt.

Specifications:
 - SoC: Qualcomm Atheros IPQ4018
 - CPU: 4x ARM Cortex A7
 - RAM: 128MB
 - Storage: 16MB NOR flash
 - Wireless
    - 2.4GHz: Built-in IPQ4018 (SoC) 802.11b/g/n 2x2:2, 2.5 dBi antennae
    - 5GHz: Built-in IPQ4018 (SoC) 802.11a/n/ac 2x2:2, 2.5 dBi antennae
 - Ethernet: Built-in IPQ4018 (SoC, QCA8075), 2x 1000/100/10Mb/s ports,
   one with 802.3af/at PoE in

Installation:
Boot the initramfs image via TFTP, then flash the sysupgrade image using
sysupgrade. Details at https://openwrt.org/toh/mikrotik/common.

Notes:
This preserves the MAC addresses of the physical Ethernet ports:
 - eth0 corresponds to the physical port labeled ETH1 and has the base
   MAC address. This port can be used to power the device.
 - eth1 corresponds to the physical port labeled ETH2 and has a MAC
   address one greater than the base.

MAC addresses are set from /lib/preinit/05_set_iface_mac_ipq40xx.sh
rather than /etc/board.d/02_network so that they are in effect for
preinit. This should likely be done for other MikroTik devices and
possibly other non-MikroTik devices as well.

As this device has 2 physical ports, they are each connected to their
respective PHYs, allowing the link status to be visible to software.
Since they are not marked on the case with any role (such as LAN or
WAN), both are bridged to the lan network by default, although this can
easily be changed if needed.

1773264a0c realtek: correct egress frame port verification
Destination switch ports for outgoing frame can range from 0 to
CPU_PORT-1.

Refactor the code to only generate egress frame CPU headers when a valid
destination port number is available, and make the code a bit more
consistent between different switch generations. Change the dest_port
argument's type to 'unsigned int', since only positive values are valid.

This fixes the issue where egress frames on switch port 0 did not
receive a VLAN tag, because they are sent out without a CPU header.
Also fixes a potential issue with invalid (negative) egress port numbers
on RTL93xx switches.

0b35a08a05 realtek: correct egress frame priority assignment
Priority values passed to the egress (TX) frame header initialiser are
invalid when smaller than 0, and should not be assigned to the frame.
Queue assignment is then left to the switch core logic.

Current code for RTL83xx forces the passed priority value to be
positive, by always masking it to the lower bits, resulting in the
priority always being set and enabled. RTL93xx code doesn't even check
the value and unconditionally assigns the (32 bit) value to the (5 bit)
QID field without masking.

Fix priority assignment by only setting the AS_QID/AS_PRI flag when a
valid value is passed, and properly mask the value to not overflow the
QID/PRI field.

For RTL839x, also assign the priority to the right part of the frame
header. Counting from the leftmost bit, AS_PRI and PRI are in bits 36
and 37-39. The means they should be assigned to the third 16 bit value,
containing bits 32-47.

SERIAL:
	WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
	The Serial setting is 115200-8-N-1. The board has a populated
	right angle 1x4 0.1" pinheader.
	The pinout is: VCC (next to J3, has little white arrow), RX, TX, GND.

This flashing procedure for the MR26 was tested with firmware:
    "22-143410M-gf25cbf5a-asa".
    U-Boot 2012.10-00063-g83f9fe4 (Jun 04 2014 - 21:22:39)

A guide how to open up the device is available on the wiki:
<https://openwrt.org/toh/meraki/mr26>

Notes:
 - The WIFI do work to a degree. Limited to 802.11bg in the 2.4GHz band.
 - the WIFI macs are made up.

0. Create a separate Ethernet LAN which can't have access to the internet.
   Ideally use 192.168.1.2 for your PC. The new OpenWrt firmware will setup
   the network via DHCP Discovery, so make sure your PC is running
   a DHCP-Server (i.e.: dnsmasq)
   '# dnsmasq -i eth# -F 192.168.1.5,192.168.1.50
   Download the openwrt-meraki-mr26 initramfs file from openwrt.org and
   rename it to something simple like mr26.bin. Then put it into the tftp's
   server directory.

1. Disassemble the MR26 device by removing all screws (4 screws are located
   under the 4 rubber feets!) and prying open the plastic covers without
   breaking the plastic retention clips. Once inside, remove the plastic
   back casing. Be careful, there some "hidden" retention clips on both
   sides of the LAN port, you need a light to see those. Next, you want to
   remove all the screws on the outer metal shielding to get to the PCB.
   It's not necessary to remove the antennas!

2. Connect the serial cable to the serial header and Ethernet patch cable
   to the device.

4. Before connecting the power, get ready flood the serial console program
   with the magic:   xyzzy  . This is necessary in order to get into the
   u-boot prompt. Once Ready: connect power cable.

5. If you don't get the "u-boot>" prompt within the first few seconds,
   you have to disconnect and reconnect the power cable and try again.

6. In the u-boot prompt enter:

   setenv ipaddr 192.168.1.4
   setenv serverip 192.168.1.2
   tftpboot ${meraki_loadaddr} mr26.bin; bootm

   this will boot a in-ram-only OpenWrt image.

7. Once it booted use sysupgrade to permanently install OpenWrt.
   To do this: Download the latest sysupgrade.bin file and move
   it to the device. Then use sysupgrade *sysupgrade.bin to install it.

    WARNING: DO NOT DELETE the "storage" ubi volume!

ae07b9cc61 ath79: tplink-archer-c6-v2-us: fix inverted LED colors
The amber and green wan led color was inverted in dts file, which ends
up leaving the wan led amber when the connection is established, so,
switch gpio led number (7 and 8) in qca9563_tplink_archer-c6-v2-us.dts.

Tip: the /etc/config/system file needs to be regenerated.

fa26cdacc2 imx: cortexa7: add support for TechNexion PICO-PI-IMX7D
TechNexion PICO-PI-IMX7D is a NXP i.MX 7Dual based development board in
the well-known "Raspberry Pi" form factor, comprising of PICO-IMX7 SoM
and the PICO-PI-IMX7D carrier board.

Usually bundled with a 5" 800x480 LVDS display with I2C touchscreen and
an Omnivision OV5645 camera on a MIPI CSI bus, on a daughterboard. The
board was previously used primarily with "Android Things" ecosystem, but
the project was killed by Google.

This would not be possible, if not for the great tutorial of setting up
Debian on this board, by Robert C. Nelson [1].

Hardware highlights:

  CPU: NXP i.MX 7Dual SoC, dual-core Cortex-A7 at 1000 MHz
  RAM: 512 MiB DDR3 SDRAM
  Storage: 4 GB eMMC
  Networking:
    - built-in Gigabit Ethernet with Atheros AR8035 PHY,
    - Broadcom BCM4339 1x1 802.11ac Wi-Fi (over SDIO) + Bluetooth 4.1
      (over SDIO + UART + IS2) combo, with Hirose u.FL connector on the
      board,
    - dual CAN interfaces on the 40-pin connector,
  Interfaces:
    - USB-C power input plus USB 2.0 OTG host/device port,
    - single USB-A host port,
    - serial console over built-in FT232BL USB-UART converter with
      micro-USB connector (configuration: 115200-8-N-1),
    - analog audio interface with TRRS connector in CTIA standard,
    - SPI, I2C and UART interfaces available on the 40-pin,
    - mikroBUS connector,
    - I2C connector for the optional touch panel,
    - parallel LCD output for the optional display,
    - MIPI CSI connector for the optional camera

Installation:

1. Connect the serial console to debug USB connector and the terminal of
   choice in another window, at 115200-8-N-1. Ensure you can switch to
   it quickly after next step.

2. Power-on the board from your PC. Ensure your PC can supply required
   current, the board can take more than 1 A in the peak load during
   booting and brownout will result in power-on reset loop. Preferably,
   use charging-capable USB port or connect through self-powered USB
   hub. If U-Boot is present already on the eMMC, interrupt the booting
   sequence by pressing any key and skip to point 7.

3. Ensure the boot mode jumpers J1 and J2 are in correct position for
   USB recovery:

       2   6  2   6
      --------------
      |o o-o||o-o o|
      |o o-o||o-o o|
   J1 -------------- J2
       1   5  1   5

   The jumpers are located just underneath the 40-pin expansion header
   and are of the smaller 2 mm pitch.

4. Download and build 'imx_usb_loader' from:
   https://github.com/boundarydevices/imx_usb_loader.

5. Power-on the board again from your PC through USB OTG connector.

6. Use 'imx_usb_loader' to load 'SPL' and 'u-boot-dtb.img' to the board:

   $ sudo imx_usb u-boot-pico-pi-imx7d/SPL
   $ sudo imx_usb u-boot-pico-pi-imx7d/u-boot-dtb.img

7. Switch to the terminal from step 2 and interrupt boot sequence by
   pressing any key within 2 seconds.

8. Configure mmc 0 to boot from the data partition and disable access to
   boot partitions:

   => mmc partconf 0 0 7 0

   This only needs to be set once. If you were running Debian previously,
   this is probably already set.

9. Enable USB mass storage passthrough for eMMC from U-boot

   => ums 0 mmc 0

10. Optionally, backup previous eMMC contents by reading out its image.

11. Copy over the factory image to the USB device, for example:

    $ sudo dd if=openwrt-imx-cortexa7-pico-pi-imx7d-squashfs.combined.bin \
      of=/dev/disk/by-id/usb-Linux_UMS_disk_0-0:0 \
      bs=8M status=progress oflag=direct

12. Detach USB MSC interface from your PC and U-Boot by pressing Ctrl+C.

13. Ensure that boot mode jumpers are at the default settings for eMMC
    boot:

       2   6  2   6
      --------------
      |o-o o||o o-o|
      |o-o o||o-o o|
   J1 -------------- J2
       1   5  1   5

   If they are not, power-off the board, restore them and power-on the
   board again. Otherwise, if jumpers are set, just reset the board from
   U-Boot CLI:

   => reset

14. The installation is now complete and board should boot successfully.

Upgrading: just use sysupgrade image, as usual in OpenWrt.

Known issues/current limitations:

- OV5645 camera - not described in upstream device tree as of kernel
  5.15. There are staging drivers present in upstream Linux tree for
  i.MX 7 CSI, MIPI-CSI and video mux, and the configuration is there in
  imx7s.dtsi - so this is expected to get supported eventually,
- on-chip ADCs are disabled in upstream device tree, so the kernel
  driver remains disabled as well.
