mmc: sdhci-esdhc-imx: Add HS400 support for iMX7ULP
Import HS400 support for iMX7ULP B0 from the Linux kernel:
2eaf5a533afd ("mmc: sdhci-esdhc-imx: Add HS400 support for iMX7ULP")
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.

* N6411-S: Baseboard with SOM N6411, eMMC, display (optional), ...
Currently U-Boot describes i.MX6UL and i.MX6ULL through separate config

the scope of these SoMs we just use a single defconfig that is compatible
with both SoCs.

write to wdog CNT register in 16 bus clocks window, if miss the

Current u-boot code is using writel() function which has a DMB

arm: imx: mx7: Move CONFIG_OPTEE_TZDRAM_SIZE from lib/optee
This config is only used by three boards with this SOC. Most other
platforms derive this information from devicetree, and are unlikely
to ever need this config.
Moreover, it is confusing when Kconfig asks for this value under

Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
This value is not used by u-boot, and it should not. The load address
of an OPTEE image is defined by said image. Either a uImage or a FIT
will have a defined load address and entry point. Those values are the
correct ones, not CONFIG_OPTEE_LOAD_ADDR.
Commit f25006b96e9f ("optee: Add CONFIG_OPTEE_LOAD_ADDR") justifies
this config by requiring its presence in u-boot's .config for other
images as part of a larger build, claiming it is "the best way".
This argument is not persuasive. U-boot's configuration is driven by
platform requirements, not the other way around. It seems more likely
that the argument is conflating tooling issues with Kconfig. Yocto and
buildroot have excellent mechanisms for defining values across the
board (pun intended). u-boot's Kconfig is the wrong place to do it.
Furthermore, it is not "best" for u-boot because it hardcodes a value
which is then not used. In fact the load address that u-boot uses is
the one derived from the OPTEE image.
Confused yet? I sure was. To prevent future confusion, remove
CONFIG_OPTEE_LOAD_ADDR.

lib: optee: Avoid CONFIG_TZDRAM_* in optee_verify_bootm_image()
The configs TZDRAM_BASE and TZDRAM_SIZE are expected to describe the
memory allocated to the OPTEE region. according to according to commit c5a6e8bd00cc ("optee: Add optee_verify_bootm_image()"). The TZDRAM is
with some limitations, described by "/reserved-memory" nodes in the
devicetree.
Consequently TZDRAM_BASE and TZDRAM_SIZE can point to imaginary
regions which have nothing to do with actual DRAM. They are not used
to configure the hardware or set up the Trust Zone Controller (TZC)
for OP-TEE -- the devicetree values are used instead.
When a valid OP-TEE image does not fall within the region described by
these configs, u-boot will refuse to load it. In fact, it mostly
serves to cause "bootm" to reject perfectly good OP-TEE images.
Ironically, someone has to correctly configure the devicetree for
TZDRAM, then go back and enter the same information in Kconfig for
"bootm". To remedy this, do not use TZDRAM_BASE and TZDRAM_SIZE in the
verification of OPTEE images.

and it is difficult to managed correctly their dependencies.
Moreover CONFIG_SPL_OPTEE is defined in common/spl/Kconfig
