f8451f144e arm64: zynqmp: Move timeout for clock propagation below psu_init
Delay required for clock propagation is tighly coupled with initialization
done in psu_init(). That's why call it also for u-boot proper with
CONFIG_ZYNQMP_PSU_INIT_ENABLED enabled.

c0adba5721 arm64: zynqmp: Add support for debug uart also for U-Boot proper
board_early_init_f() is the right location where debug uart can be
configurated (after MIO initialization).
The patch is taking this call from SPL to also make it available for U-Boot
proper.

f1433d0dc9 arm64: zynqmp: Add third backup bootmode
I found this issue when was running py/test.py on zcu102 which is for me by
default setup to SD boot mode without any way to change boot mode.
Alternative software bootmode selection to JTAG is not working because JTAG
mode is 0 which also reset value for it. That's why saying SPL to take
u-boot.itb from RAM instead of SD in SD boot mode is not possible via
alternative bootmode selection.
That's why setup third boot mode to JTAG(BOOT_DEVICE_RAM) as final
fallback.

3b26c860d3 arm: zynqmp: Wire SPL/ATF handoff structure properly
handoff_setup() was used to generate fixed handoff structure for ATF on
ZynqMP platform.
Switching to bl2_plat_get_bl31_params() platform brings more flexibility
because information can be taken from fit image where /fit-images node is
created at run time.

Empty implementation should not return 0 (success) because that mean that
passed name matches the board configuration.

de79ca9512 arm64: zynqmp: Add board_boot_order for MMC boot extension
In past SPL_ZYNQMP_TWO_SDHCI symbol was introduced to handle boards with
two sdhci controllers. The problem was that U-Boot is registering
controllers based on aliases in DT but bootmode targets specific controller
ID. That's why on boards with one "second" sdhci controller bootmode was
pointing to second controller(MMC2) but alias was setup to mmc0 (the first
controller). And SPL requires to point to mmc0 in this case.

Long time ago commit f101e4bd37
("spl: add support for alternative boot device") added support for handling
multiple bootmodes in SPL. Use this functionality and setup second sdhci
controller as backup boot device.

Below is table with behavior:
HW/bootmode  bootorder
sd0/sd0      mmc0/mmc1 (mmc1 never called)
sd1/sd1      mmc1/mmc0 (mmc0 fails and mmc1 is called)
sd0+sd1/sd0  mmc0/mmc1 (mmc1 never called)
sd0+sd1/sd1  mmc1/mmc0 (mmc0 never called)

All other bootmodes are not affected but order can be extended to cover
advance boot flows.

e82024def6 arm64: zynqmp: Do not assing MIO34 that early on zcu100
MIO34 is connected to POWER_KILL signal. When MIO configuration is done in
psu_init() and this pin is assigned to PMU but PMU configuration is not
loaded yet. PMU gpio output is high that means board is powered off
immediately.
The patch is fixing this sequence that MIO34 stays assing to ps gpio IP.
PMU config is loaded in SPL and then pin assigned to PMU through
psu_post_config_data().

724caaba4c arm64: zynqmp: Do not call bss init and board_init_r from board_init_f
There is no reason to clear bss and call board_init_r() from board_init_f()
beca it can be called directly from crt0_64.S with also support for SPL
stack relocation to SDRAM.
For more information please take a look at arch/arm/lib/crt0_64.S

350cfe79a8 arm64: zynqmp: fix preprocessor check for SPL_ZYNQMP_TWO_SDHCI
A missing CONFIG_ prefix while checking for this Kconfig variable makes the
check always fail. Fix it. While there also switch from the '#if defined'
form to the '#ifdef' form as the other checks in this function.

35e2b92344 arm64: zynqmp: Fix logic around CONFIG_ZYNQ_SDHCI
Replace SDHCI controller listing by Kconfig symbol to let SPL know that
this board is using multiple SDHCIs controllers.
Kconfig help message should explain why this is needed.
Origin symbols were used in full u-boot but with moving to distro boot
this was fixed already.

Similar changes was done for Zynq in past and this patch just follow
this pattern to separate cpu code from SoC code.

Move arch/arm/cpu/armv8/zynqmp/* -> arch/arm/mach-zynqmp/*
And also fix references to these files.
