When the imx8mn.dtsi file was pulled in from Linux, the UARTs
were moved into an spba sub-node which wasn't being included
in the SPL device tree. This meant the references to the UART
weren't being handled properly and when booting the system would
constantly reboot. Fix this by adding the spba node to the spl
device tree to restore normal booting.
Based on the patch from Adam Ford for the imx8mn-beacon-kit-u-boot
board.

After we switch to use BINMAN_SYMBOLS, there is no need to pad
the file size to 0x8000 and 0x4000. After we use BINMAN_SYMBOLS,
the u-boot-spl-ddr.bin shrink about 36KB with i.MX8MP-EVK.

We are migrating to use binman symbols, the current names are
inconsistent across different boards, so unify them.
Also add `type = "blob-ext";`, since the new names are not valid binman
types.

Mark pinctrl_wdog as u-boot,dm-spl to clean up board code,
The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.

As suggested in commit 028abfd9b1 ("imx8mm-evk: Generate a single
bootable flash.bin again") for imx8mm_evk, it is possible to produce
single bootable image via binman. This restores the original behavior in
distros, where only one boot container is used to create target image.
Perform similar adaptions in order to provide single bootable image for
imx8mn-ddr4-evk derivate.
Update documentation to drop additional step of copying u-boot.itb

Add DEK blob encapsulation support for IMX8M 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

Enable this support across the entire i.MX8M family by providing quirks
to usdhc controllers designated by storage media connected to them.

Some SD Card controller and power circuitry has increased capacitance,
which keeps the internal logic remains powered after regulator is switch
off. This is generally the case when card is switched to SD104 mode,
where a power cycle should be performed. In case if the card internal
logic remains powered, it causes a subsequent failure of mode
transition, effectively leading to failed enumeration.
Introduce a delay of 20 msec in order to provide a possibility for
internal card circuitry to drain voltages and perform a power cycle
correctly.
Similar fix is done in commit c49d0ac38a ("ARM: dts: rmobile: Increase
off-on delay on the SD Vcc regulator") targeted Renesas SOCs.

Board files should not re-implement do_reset() to work around this
function not being defined in for specific configurations. Rather,
the fix is to compile in drivers which implement this properly.
This patch enables sysreset and watchdog drivers in SPL and ties
them together to implement the same as the do_reset() hack in the
board file, except correctly in the DM/DT framework.
