According to arch/arm/lib/crt0_64.S, the BSS section is "UNAVAILABLE"
and uninitialized before relocation. Also, it overlaps with the
appended DTB before relocation, so writing data into a variable
in the BSS section might corrupt the appended DTB.
Unfortunately, pinctrl-apq8016.c and pinctrl-apq8096.c do place the
"pin_name" variable in the BSS section (since it's uninitialized).
It's also used before relocation, when setting up the pinctrl for
the serial driver.
On DB410c this causes "GPIO_5" to be written into some part of an
appended DTB, e.g.:
80111820: edfe0dd0 9f100000 38000000 c00e0000 ...........8....
80111830: 28000000 11000000 10000000 00000000 ...(............
80111840: 4f495047 8800355f 00000000 00000000 GPIO_5..........
80111850: 00000000 00000000 01000000 00000000 ................
80111860: 03000000 04000000 00000000 02000000 ................
80111870: 03000000 04000000 0f000000 02000000 ................
80111880: 03000000 2d000000 1b000000 6c617551 .......-....Qual
80111890: 6d6d6f63 63655420 6c6f6e68 6569676f comm Technologie
Depending on the part of the DTB that is corrupted this might not
cause any problems, but it can also result in strange reboots
without any serial output.
Fortunately, in practice this does not cause issues on DB410c yet
because board_fdt_blob_setup() in dragonboard410c.c currently
overrides the appended DTB with the one passed by the previous
bootloader (LK) (which does not get corrupted).
DB820c does not have board_fdt_blob_setup() so I would expect it to
be affected by this problem. Perhaps everyone was just fortunate to
not compile an U-Boot configuration where the pin_name corrupts an
important part of the DTB.
Make sure "pin_name" is explicitly placed in the .data section
instead of .bss to fix this.

The sysinfo_get_str() implementation checks whether the sysinfo was even
detected. In U-Boot proper, sysinfo_detect() is not called anywhere but
on one specific board. Call sysinfo_detect() before sysinfo_get_str() to
make sure the sysinfo is detected and sysinfo_get_str() returns valid
value instead of -EPERM.

Replace uclass_first_device_err(UCLASS_SYSINFO, &dev) with sysinfo_get(&dev).
The board_info code may use sysinfo to print board information, so use the

as return uclass_first_device_err(UCLASS_SYSINFO, &dev) anyway, so there is

Nomadik GPIO is a fairly simple GPIO module used in the ST-Ericsson
Ux500 SoCs (and some older Nomadik SoCs). It uses registers where
each GPIO is represented as a single bit, plus "set" and "clear"
registers that allow updating the state without having to read the
existing state.
The driver implements support for it for use together with DM_GPIO
and the existing ste-dbx5x0.dtsi device tree.

The original U-Boot port for the ST-Ericsson U8500 SoC was dropped
in commit 68282f55b8 ("arm: Remove unused ST-Ericsson u8500 arch").
Most of the drivers related to the old port were removed, but the
db8500_gpio.c driver was forgotten for some reason. There is no way
to select it and it does not compile anymore because of missing
headers, so let's just remove it.
The new port for U8500 introduced in commit 689088f9da
("arm: Add support for ST-Ericsson U8500 SoC") fully embraces the
new Driver Model and device trees where possible, so this is
preparation to add a new, simplified GPIO driver based on DM_GPIO.

The default implementation of checkboard() calls the
nxp_board_rev_string() function
to retrieve a character representing the revision number of the board.
However, this
attempt to retrieve the revision number may fail in certain situations or be
otherwise undesirable.
There is already a configuration option to avoid retrieving the
revision number of
the board: CONFIG_NXP_BOARD_REVISION. In fact, if this option is enabled, the
nxp_board_rev_string() function's definition will be omitted entirely,
meaning that the previous implementation of checkboard() would result
in a linker error.
This changeset makes the default implementation of checkboard() respect the
CONFIG_NXP_BOARD_REVISION configuration option, only attempting to retrieve
the board revision number if that option is defined.

In case the iMX8M boot from eMMC boot partition and the primary image
is corrupted, the BootROM is capable of starting a secondary image in
the other eMMC boot partition as a fallback.
However, the BootROM leaves the eMMC BOOT_PARTITION_ENABLE setting as
it was, i.e. pointing to the boot partition containing the corrupted
image, and the BootROM does not provide any indication that this sort
of fallback occured.
According to AN12853 i.MX ROMs Log Events, Rev. 0, May 2020, it is
possible to determine whether fallback event occurred by parsing the
ROM event log. In case ROM event ID 0x51 is present, fallback event
did occur.
This patch implements ROM event log parsing and search for event ID
0x51 for all iMX8M SoCs, and based on that corrects the eMMC boot
partition selection. This way, the SPL loads the remaining boot
components from the same eMMC boot partition from which it was
started, even in case of the fallback.

When using uclass_get_device* to get the FEC device we need to use
device sequence instead of index into UCLASS_ETH. In systems where for
example a I2C based DSA switch exists it will probe before the FEC
master and its ports will be registered first and have the first
indexes yet the FEC's sequence comes from the device-tree alias.
Take for example the imx8mm-venice-gw7901 board which has an i2c based
DSA switch:
u-boot=> net list
eth1 : lan1 00:0d:8d:aa:00:2f
eth2 : lan2 00:0d:8d:aa:00:30
eth3 : lan3 00:0d:8d:aa:00:31
eth4 : lan4 00:0d:8d:aa:00:32
eth0 : ethernet@30be0000 00:0d:8d:aa:00:2e active
Thus in this case uclass_get_device(UCLASS_ETH, 0, &dev) returns lan1
which is wrong but uclass_get_device_seq(UCLASS_ETH, 0, &dev) returns
ethernet@30be000 which is correct.
