Distro Boot requires a U-Boot-specific script named boot.scr or
boot.scr.uimg which contains boot commands to boot the system. The
boot.cmd is such a file. Use mkimage to generate boot.scr or
boot.scr.uimg from boot.cmd, and the command is:
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Distro Boot Script" -d boot.cmd boot.scr.uimg
The boot.cmd file is an example script and can be modified based on
needs. bootargs is set in this script and root uses the default value
"/dev/mmcblk1p2 rootwait rw" which can be changed by overriding mmcroot.

When using cygwin64 "dd (coreutils) 8.26 Packaged by Cygwin (8.26-2)",
the last not 512bytes aligned data wat cut off and not burned into SD
card.
Saying the flash.bin size is 1085608 bytes, not 512bytes aligned. It only
burned 1085440 bytes, the leaving 168 bytes were not burnned and cause
boot issue.
So update README dd command to add "conv=notrunc"

Quoting Ye Li from NXP:
"We have confirmed with PMIC team, 0x35 is used only on early chips
and not used any more. 0x25 is the final address."
Fix it by merging power_pca9450a_init and power_pca9450b_init into one
function power_pca9450_init.

Current codes assume the OPTEE address is at the end of first DRAM bank.
Adjust the process to allow OPTEE in the middle of first bank.
When OPTEE memory is removed from first bank, it may split the first bank
to two banks, adjust the MMU table for the split case,
Since the default CONFIG_NR_DRAM_BANKS is 4, it is enough, just enlarge
i.MX8MP evk to default to avoid issue.

In uMCTL2 Databook, for LPDDR4, it is recommended to set
this register to 1. This can avoid ddr bandwidth is lower

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Use the `do_reset` implementation of `arch/arm/lib/reset.c` in SPL
instead. It is very close to what is done here, anyway, and plays
more nicely with the rest of U-Boot than adding a custom `do_reset`
implementation into board files.
`do_reset` from `arch/arm/lib/reset.c` calls `reset_cpu` with 0 as the
addr parameter while the boards are passing WDOG1_BASE_ADDR. This is
ok because the `reset_cpu` implementation uses WDOG1_BASE_ADDR by
default if 0 is passed in.

At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.
