4a1b975dac board: stm32mp1: reserve memory for OP-TEE in device tree
Add reserve memory for OP-TEE in U-Boot and in kernel device tree:
- no more reduce the DDR size in "memory" node:
  CONFIG_SYS_MEM_TOP_HIDE is no more used
- U-Boot device-tree defines the needed "reserved-memory" for OP-TEE
  and U-Boot should not use this reserved memory: board_get_usable_ram_top
  use lmb lib to found the first free region, the not reserved
  memory, enough to relocate U-Boot: the needed size of U-Boot
  is estimated with gd->mon_len + CONFIG_SYS_MALLOC_LEN.
- the optee node ("optee@...": firmware with compatible "linaro,optee-tz")
  and the associated "reserved-memory" are deactivated in kernel device
  tree when OP-TEE is not detected by U-Boot to prevent kernel issue
  (memory is reserved but not used, optee driver probe failed).

e519f03a18 cmd: mem: Remove CONFIG_SYS_MEMTEST_SCRATCH mapping
There is no real need to exactly define space for saving patterns for
alternate memory test. It is much easier to allocate space on the stack and
use it instead of trying to find out space where pattern should be saved.

For example if you want to test the whole DDR memory you can't save patter
to DDR and you need to find it out. On Xilinx devices DDR or OCM addresses
were chosen but that means that OCM needs to be mapped and U-Boot has
access permission there.

It is easier to remove this limitation and simply save it on stack because
it is very clear that memory test can't rewrite U-Boot and U-Boot has also
full access to memory where runs from.

ac5769cba1 stm32mp1: remove fdt_high and initrd_high in environment
Remove fdt_high and initrd_high (set to 0xffffffff) in stm32mp1 board
enviromnent, and U-Boot always relocate FDT and initrd in bootm command.

This relocation is limited by CONFIG_SYS_BOOTMAPSZ which indicates
the size of the memory region where it is safe to place data passed
to the Linux kernel (DTB, initrd), it is
a) Less than or equal to RAM size.
b) not within the kernel's highmem region

So 256M seems large enough in most circumstances and users
can override this value via environment variable "bootm_mapsize"
if needed.

This modification increases the boot time but avoid assumption
on aligned address for bootm command.

A user can still define this variables themselves if the FDT or
initrd is either left in-place or copied to a specific location.

+ fdt_addr_r: A size of 1MB for the FDT/DTB seems reasonable.
+ ramdisk_addr_r: It is recommended that this location be highest in RAM
                  out of fdt_addr_, kernel_addr_r, and ramdisk_addr_r,
                  so that the RAM disk can vary in size and use any

For suggestions on memory locations for ARM systems, you must follow
the guidelines specified in Documentation/arm/Booting
in the Linux kernel tree.

And in sources/linux-stm32mp/Documentation/arm/Booting

The zImage may also be placed in system RAM and called there.  The
kernel should be placed in the first 128MiB of RAM.  It is recommended
that it is loaded above 32MiB in order to avoid the need to relocate
prior to decompression, which will make the boot process slightly
faster.

4549e789c1 SPDX: Convert all of our multiple license tags to Linux Kernel style
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 multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.
