Currently CONFIG_OF_SEPARATE is completely broken and U-Boot for some
mpc85xx board (e.g. P2020) has to be compiled with CONFIG_OF_EMBED.
Otherwise it crashes during early init.
When debug console is enabled and all debug logging options are turned on
then U-Boot on P2020 with CONFIG_OF_SEPARATE prints following error:
No valid device tree binary found at 110dc300
initcall sequence 110d3560 failed at call 1109535c (err=-1)
### ERROR ### Please RESET the board ###
Problem is with appended DTB. When CONFIG_SYS_MPC85XX_NO_RESETVEC is set
U-Boot binary image without DTB ends immediately after the .u_boot_list
section. At this position is defined _end symbol at which U-Boot expects
start of the appended DTB.
Problem is that after .u_boot_list section are in linker script defined
another sections with 256 byte long padding which are completely empty.
During conversion of U-Boot ELF binary to RAW binary u-boot-nodtb.bin,
objcopy removes trailing zero padding and therefore DTB is appended at
wrong position.
Changing alignment from 256 bytes to 4 bytes fixes this issue. And appended
DTB is finally at he correct position. With this fix U-Boot on P2020 with
CONFIG_OF_SEPARATE option starts working again.

If env is stored on SD card then U-Boot SPL automatically calls mmc_init()
before it is going to load proper U-Boot from SD card.
If env is not stored on SD card then U-Boot SPL fails to read proper U-Boot
from SD card due to missing mmc_init() call.
So add missing mmc_init() call into fsl_esdhc_spl's mmc_boot() function.

mmc_init() returns early if card was already initialized, so there is no

In pre-PBL header is stored size of code which BootROM copies from SD card

There are two different implementations to do a secure monitor call:

seems to be an ad-hoc implementation. The latter is imported from linux.
smc_call() is also only available if CONFIG_ARMV8_PSCI is not defined.
This makes it impossible to have both PSCI calls and PSCI implementation
in one u-boot build. The layerscape SoC code decide at runtime via
check_psci() if there is a PSCI support. Therefore, this is a
prerequisite patch to add PSCI implementation support for the layerscape
SoCs.

The impedance of the QSPI PCB lines on the sama7g5ek is 50 Ohms.
Align the output impedance of the QSPI0 HSIOs by setting a medium drive
strength which corresponds to an impedance of 56 Ohms when VDD is in the
3.0V - 3.6V range. The high drive strength setting corresponds to an
output impedance of 42 Ohms on the QSPI0 HSIOs.
This is just a fine tunning. The memory that we have populated on sama7g5ek
works fine even with high drive strength, but it's better to adjust it and
use medium instead, in case some other flashes with higher frequencies are

To quote the author:
The bootflow feature provide a built-in way for U-Boot to automatically
boot an Operating System without custom scripting and other customisation.
This is called 'standard boot' since it provides a standard way for
U-Boot to boot a distro, without scripting.
It introduces the following concepts:
- bootdev - a device which can hold a distro
- bootmeth - a method to scan a bootdev to find bootflows (owned by
U-Boot)
- bootflow - a description of how to boot (owned by the distro)
This series provides an implementation of these, enabled to scan for
bootflows from MMC, USB and Ethernet. It supports the existing distro
boot as well as the EFI loader flow (bootefi/bootmgr). It works
similiarly to the existing script-based approach, but is native to
U-Boot.
With this we can boot on a Raspberry Pi 3 with just one command:
bootflow scan -lb
which means to scan, listing (-l) each bootflow and trying to boot each
one (-b). The final patch shows this.
With a standard way to identify boot devices, booting become easier. It
also should be possible to support U-Boot scripts, for backwards
compatibility only.
