efe19295a5 km: common: implement field fail-safe u-boot update
This patch provides possibility for field fail-safe u-boot updates.
The implementation can be used on all pg-wcom boards that are booting from
parallel NOR flash.

When used in a board design, provided check_for_uboot_update function will
start new u-boot at defined location if updateduboot envvar is set to yes.
With this implementation it is expected that factory programmed u-boot
will always stay as it is, and optionally new u-boot can be safely
programmed by embedded software when the unit is rolled out on the field.

It is expected check_for_uboot_update to be called early in execution
before relocation (*_f) once SoC is basically initialized and environment
can be read, with this possibilities to not be able to fix a u-boot bug by
a u-boot update are reduced to minimum.

de144d5ffe km: qrio: add access functions for ebootcount
The EBOOTCNT is a reserved persistent static memory area in QRIO,
and similar to BOOTCNT is intended to be used as boot counter location.

Comparable to BOOTCNT that is reserved for u-boot main bootcount
infrastructure, EBOOTCNT is intended to be used for pg-wcom board
specific purposes (e.g implementing early boot counter for fail-safe
u-boot update).

70003e52f4 km/ls102xa: dbg phy prst depends on piggy presence
The PHY for the debug interface was placed on the board for the
pg_wcom_ls102x. Hence only when a piggy is plugged, a RJ45 jack
including magnetics is connected to the MDI of the PHY. Without a
piggy the MDI lines are left floating and it does not make sense to
have an active debug PHY.
In case of expu1 an active PHY without a piggy even led to increased
jitter for syncE.

This patch only deactivates the prst line of the debug PHY when a piggy
is detected persent.

f8753f025f pylint: Adjust how the output is produced
The current Makefile rule requires there to be a 'Module' line in the
pylint output, like this:

   ************* Module binman.fip_util

This line only appears if pylint has some comments about the module. We
cannot rely on it for naming.

Update the code to instead use the filename as the identifier for each
score, so rather than:

   multiplexed_log 7.49

we output:

   test_multiplexed_log.py 7.20

It is still easy to see which file the score relates to. In fact the new
naming is nicer since the full subdirectories are shown.

The avoids the problem where a module name is not produced, and the output
gets out of sync.

Regenerate pylint.base so we can start from the current baseline.

82a9e13a9b tools: kwboot: Improve retrying logic for incomplete xmodem packets
Sometimes if the first byte of xmodem packet (SOH) is incorrectly
transmitted, BootROM sends NAK for every non-SOH received byte, which
makes BootROM and the host kwboot tool out of sync. BootROM automatically
re-synchronizes after 2s pause by dropping its input queue. So when
attempting retransmit for 9th time or later, ignore NAK reply from BootROM
and either wait for valid ACK or let kwboot timeout, which implies
re-synchronization.

This fixes retransmission of xmodem packets and allows kwboot to work also
without "Waiting ... and flushing tty" code which is at the beginning of
kwboot xmodem transfer.

fcc87efdf3 binman: Skip node generation for images read from files
We can and should run the node generator only when creating a new image.
When we read it back, there is no need to generate nodes - they already
exits, and binman does not dive that deep into the image - and there is
no way to provide the required fdt-list. So store the mode in the image
object so that Entry_fit can simply skip generator nodes when reading
them from an fdtmap.

This unbreaks all read-backs of images that contain generator nodes in
their fdtmap. To confirm this, add a corresponding test case.

6c928c63a1 moveconfig: Fix code relying on now-stripped newline characters
Commit 37f815cad0 ("moveconfig: Use a function to read files") adds a
helper function that can read a file as lines, but strips the newline
characters. This change broke parts of moveconfig code that relied on
their existence, resulting in a few issues:

Configs that are defined as empty aren't removed from header files (e.g.
"#define CONFIG_REMAKE_ELF"). Make regex patterns use '\b' to match word
boundaries instead of '\W' (which matched the newlines) so these lines
still match and get removed.

All changes in defconfig are considered removed by savedefconfig even
if they weren't, and line continuations in the headers aren't recognized
and removed properly, because their checks explicitly look for a newline
character. Remove the character from both comparisons.

The printed diff of header files is wrongly formatted and raises an
IndexError if a blank line was removed. Let print() print the new lines,
and use size-independent ways to check strings to fix the diff output.

50d5c6428f mkimage: sunxi_egon: Allow overriding the padding size
Due to a bug in the H3 SoC, where the CPU 0 hotplug flag cannot be
written, resuming CPU 0 requires using the "Super Standby" code path in
the BROM instead of the hotplug path. This path requires jumping to an
eGON image in SRAM.

This resume image, whose single purpose is to jump back to the secure
monitor, only needs to contain a single instruction. Padding the image
to 8 KiB would be wasteful of SRAM. Hook up the -B (block size) option
so users can set the block/padding size.

For sunxi boards with the AXP209, AXP221, AXP809, and AXP818 PMICs

PocketCHIP.
This provides a configurable option to check if bit 0 of
register 0 of the PMIC says it was powered because of a power button
press (0) or a plug-in event (1). If the value is 1 and this option
is selected, the device shuts down shortly after printing a message
to console stating the reason why it's shutting down. Powering up the
board with the power button is not affected.

78592c094e pmic: axp: define ALDO_IN startup bit
Most AXP PMICs feature a "startup source" register, which keeps
information about how the PMIC started operation. Bit 0 in there means
it has been started by "plugging in the power cable".

Define a symbol in each PMIC's header file to be able to use that
register and bit later on.

8695b5111c sunxi: gpio: Fix up pointer arithmetic
The calls for flipping bits in the Allwinner pin controller registers
were using unnecessarily complex pointer arithmetic.

Improve readability by simplifying the expression.

fb6f67013e mmc: sunxi: Use DM_GPIO flags to set pull-up
Now that the sunxi_gpio driver handles pull-up/down via the driver
model, pin configuration does not need a platform-specific function.

This, along with gpio_flags_xlate(), allows the GPIO driver to handle
pull-up/down flags provided by consumer drivers or in the device tree.

efdd656659 sunxi: gpio: Add per-bank drive and pull setters
The GPIO and pinctrl drivers need these setters for pin configuration.
Since they are DM drivers, they should not be using hardcoded base
addresses. Factor out variants of the setter functions which take a
pointer to the GPIO bank's MMIO registers.

The return values of these functions are always zero, and they are
never checked. Since they are not needed, remove them.
