NXP used to setup the gpmi clock root from gpmi_clk in early versions
in their downstream BSP. [1]
However on mainline the gpmi clock root was always setup from enfc
since the beginning of the i.MX 6 series SoCs, which is still the same
today. [2]
NXP followed the mainline approach at some point and changed
setup_gpmi_io_clk to setup gpmi clock root from enfc which left faulty
code behind in our board file. [3]
This commit follows the change of NXP as it improves the performance of
the NAND from ~1.2 MiB/s to ~12 MiB/s. [3]
This change was verified to work in recovery-mode and u-boot loaded
from NAND on all four Colibri iMX6ULL SKUs from Toradex.
The frequency used to read the NAND, measured on RE# (Read Enable):
before this patch: 1.4 MHz
after this patch: 22 MHz
in Linux Kernel: 50 MHz

Finally, found the root cause of the issue already once mentioned back
here [2] which caused the following error message during boot:
imx_wdt watchdog@30280000:
pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
Turns out while the watchdog node itself was already u-boot,dm-spl its
pinctrl node was not which caused it to be unavailable at that early
stage. Note that any and all other boards I checked also seem to be
missing this. However, I can't judge whether or not they might indeed
need a similar fix or not.

Variable "kernel_image" is used in boot.scr script only, that sets its
own default value to the constant string @@KERNEL_IMAGETYPE@@ in case
"kernel_image" is not set.
The default name of the kernel image shipped with BSP 5.x is "Image.gz".
Setting kernel_image="Image" as a pre-defined u-boot variable
breaks booting systems with modern versions of boot.scr, whereas
renaming it fixes booting with modern scripts and does not break working
of earlier versions of boot.scr.

Prepare for DEK blob encapsulation support through "dek_blob" command.
On ARMv8, u-boot runs in non-secure, thus cannot encapsulate a DEK blob
for encrypted boot.
The DEK blob is encapsulated by OP-TEE through a trusted application
call. U-boot sends and receives the DEK and the DEK blob binaries
through OP-TEE dynamic shared memory.
To enable the DEK blob encapsulation, add to the defconfig:
CONFIG_SECURE_BOOT=y
CONFIG_FAT_WRITE=y
CONFIG_CMD_DEKBLOB=y
Taken from NXP's commit 56d2050f40 ("imx8m: Add DEK blob encapsulation

Even if board can be successfuly built, CI goes in deadlock (see thread
on https://www.mail-archive.com/u-boot@lists.denx.de/msg419663.html).
This is caused by SYS_CONFIG set in header file and because defconfig

Hex and int Kconfig options are supposed to have defaults. This is so we
can configure U-Boot without having to enter particular values for the
items that don't have specific values in the board's defconfig file.
If this rule is not followed, then introducing a new Kconfig can produce
a loop like this:
Break things (BREAK_ME) [] (NEW)
Error in reading or end of file.
Break things (BREAK_ME) [] (NEW)
Error in reading or end of file.
The continues forever since buildman passes /dev/null to 'conf', and
the build system just tries again. Eventually there is so much output that
buildman runs out of memory.
We can detect this situation by looking for a symbol (like 'BREAK_ME')
which has no default (the '[]' above) and is marked as new. If this
appears multiple times in the output, we know something is wrong.
Add a filter function for the output which detects this situation. Allow
it to return True to terminate the process. Implement this termination in
cros_subprocess.
With this we get a nice message:
buildman --board sandbox -T0

At present buildman does not write any output (to the 'out' and 'err)
files if the build terminates with a fatal error. This is to avoid adding
lots of spam to the logs.
However there are times when this is actually useful, such as when the
build fails for an obscure reason such as a Kconfig loop.
Update the logic to always write the output, so that the user gets a clue
as to what is happening.

Bulletproof the default boot command with reset statements in case
any command in the chain would fail. In case a failure were to happen,
the board will reset, increment boot counter and retry the procedure.
In case the failures persist and the boot counter reaches the bootlimit,
U-Boot starts altbootcmd instead of the default bootcmd boot command.
The altbootcmd swaps the default boot partition for the other boot
partition, which is an identical copy or an older copy, and tries
booting from that one instead.

According to IC suggest, need to clear the STROBE_DLL_CTRL_RESET
before any setting of STROBE_DLL_CTRL register.
USDHC has register bits(bit[27~20] of register STROBE_DLL_CTRL)
for slave sel value. If this register bits value is 0, it needs
256 ref_clk cycles to update slave sel value. IC suggest to set
bit[27~20] to 0x4, it only need 4 ref_clk cycle to update slave
sel value. This will short the lock time of slave.
i.MX7ULP B0 will need more time to lock the REF and SLV, so change
to add 5us delay.
