U-Boot needs to link ps7_init_gpl.c on Zynq or psu_init_gpl.c on
ZynqMP (PS init for short). The current logic to locate this file for
both platforms is:
1. if a board-specific file exists in
board/xilinx/zynq[mp]/$(CONFIG_DEFAULT_DEVICE_TREE)/ps?_init_gpl.c
then use it
2. otherwise use board/xilinx/zynq/ps?_init_gpl.c
In the latter case the file does not exist in the U-Boot sources and
must be copied in the source tree from the outside before starting the
build. This is typical when it is generated from Xilinx tools while
developing a custom hardware. However making sure that a
board-specific file is _not_ found (and used) requires some trickery
such as removing or overwriting all PS init files (e.g.: the current
meta-xilinx yocto layer).
This generates a few problems:
* if the source tree is shared among different out-of-tree builds,
they will pollute (and potentially corrupt) each other
* the source tree cannot be read-only
* any buildsystem must add a command to copy the PS init file binary
* overwriting or deleting files in the source tree is ugly as hell
Simplify usage by allowing to pass the path to the desired PS init
file in kconfig variable XILINX_PS_INIT_FILE. It can be an absolute
path or relative to $(srctree). If the variable is set, the
user-specified file will always be used without being copied
around. If the the variable is left empty, for backward compatibility
fall back to the old behaviour.
Since the issue is the same for Zynq and ZynqMP, add one kconfig
variable in a common place and use it for both.
Also use the new kconfig help text to document all the ways to give
U-Boot the PS init file.
Build-tested with all combinations of:
- platform: zynq or zynqmp
- PS init file: from XILINX_PS_INIT_FILE (absolute, relative path,
non-existing), in-tree board-specific, in board/xilinx/zynq[mp]/
- building in-tree, in subdir, in other directory

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This patch adds new command "zynqmp" to handle zynqmp
specific commands like "zynqmp secure". This secure command is
used for verifying zynqmp specific secure images. The secure
image can either be authenticated or encrypted or both encrypted
and authenticated. The secure image is prepared using bootgen
and will be in xilinx specific BOOT.BIN format. The optional
key can be used for decryption of encrypted image if user
key was specified while creation BOOT.BIN.

There is a need to include psu_init also in mini u-boot configuration

CONFIG_SYS_CONFIG_NAME is not proper config option for different low
level init files because different board revisions requires different
psu_init_gpl* files.
Also at the end of moving drivers to DM all board specific configuration
files should be removed.
The same changes was done for Zynq.

Support RAM and MMC boot mode in SPL also with SPL_FIT images.
In MMC boot mode two boot options are available:
1) Boot flow with ATF(EL3) and full U-Boot(EL2):
aarch64-linux-gnu-objcopy -O binary bl31.elf bl31.bin
mkimage -A arm64 -O linux -T kernel -C none -a 0xfffe5000 -e 0xfffe5000
-d bl31.bin atf.ub
cp spl/boot.bin <sdcard fat partition>
cp atf.ub <sdcard fat partition>
cp u-boot.bin <sdcard fat partition>
2) Boot flow with full U-Boot(EL3):
cp spl/boot.bin <sdcard>
cp u-boot*.img <sdcard>
3) emmc boot mode
dd if=/dev/zero of=sd.img bs=1024 count=1024
parted sd.img mktable msdos
parted sd.img mkpart p fat32 0% 100%
kpartx -a sd.img

psu_init() function contains low level SoC setup generated for every HW
design by Xilinx design tools. xil_io.h is only supporting file to fix
all dependencies from tools. The same solution was used on Xilinx Zynq.
The patch also change CONFIG_SYS_INIT_SP_ADDR to the end of OCM which
stays at the same location all the time.
Bootrom expects starting address to be at 0xfffc0000 that's why this
address is SPL_TEXT_BASE.
