mx7ulp: wdog: Wait for WDOG unlock and reconfiguration to complete
According to i.MX7ULP Reference Manual we should wait for WDOG unlock
and reconfiguration to complete.
Section "59.5.3 Configure Watchdog" provides the following example:
DisableInterrupts; //disable global interrupt
WDOG_CNT = 0xD928C520; //unlock watchdog
while(WDOG_CS[ULK]==0); //wait until registers are unlocked
WDOG_TOVAL = 256; //set timeout value
WDOG_CS = WDOG_CS_EN(1) | WDOG_CS_CLK(1) | WDOG_CS_INT(1) |
WDOG_CS_WIN(0) | WDOG_CS_UPDATE(1);
while(WDOG_CS[RCS]==0); //wait until new configuration takes effect
EnableInterrupts; //enable global interrupt
Update U-Boot WDOG driver to align with i.MX7ULP reference manual.
Use 32 bits accessing to CS register. According to RM, the bits in
this register only can write once after unlock. So using 8 bits access
will cause problem.

mx6sabresd: Make checkboard respect CONFIG_NXP_BOARD_REVISION
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

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.

ARM: imx: Pick correct eMMC boot partition from ROM log
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.

net: fec: use device sequence vs index when fetching fec
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

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

eth0 : ethernet@30be0000 00:0d:8d:aa:00:2e active
