c01f594995 arm64: zynqmp: Add MTD partition handling for dfu_alt_info generation
Generate dfu_alt_info generation based on information from MTD partitions.
mtd_found_part() is trying to identify MTD partition which code is running
from. If partitions are not defined and location is not found it is going
to previous behavior.

097ccdf962 xilinx: Do not call private env_get_location() when !ENV_IS_NOWHERE
Private function for finding out location of environment is not working
when ENV_IS_NOWHERE is disabled.
The reason is that current fallback is ENVL_UNKNOWN when
CONFIG_ENV_IS_NOWHERE is not enabled. The code could be updated like this

-               return ENVL_NOWHERE;
+               if (IS_ENABLED(CONFIG_ENV_IS_NOWHERE))
+                       return ENVL_NOWHERE;
+               return ENVL_UNKNOWN;

But then boot is still not working because ENVL_UNKNOWN has no driver and
env_init() returns -ENODEV. That's why it is better not to define board
specific env_get_location() because then weak env_get_location() is used
which is going over env_locations[] and returning locations which are
actually enabled in u-boot instance.

2c8a09219c arm64: zynqmp: Add multiboot support for SPL/SPI offset calculation
In case of A/B update systems there should be an option to load the same
binary/binaries to different location and they should work.
Before this patch boot.bin with U-Boot SPL can be added to whatever 32k
offset in SPI and SPL finds u-boot.itb at CONFIG_SYS_SPI_U_BOOT_OFFS
offset. In case of A/B update systems that means that SPL is at different
locations but it still points to the same u-boot.itb which is not correct.
That's why include multiboot value to offset calculation to be able to
point to image from the same base.
It doesn't affect any current system which starts from 0 offset.

This patch also change Kria defconfig which uses A/B setup. Partition
A starts at multiboot 64, partition B at multiboot 496.

And also print message about used SPI offset which is useful for all cases.

a32c3e9e4f arm64: xilinx: Move board_get_usable_ram_top() to common location
The commit ce39ee28ec ("zynqmp: Do not place u-boot to reserved memory
location") adds functionality for ZynqMP to read reserved memory node and
do not place U-Boot to reserved location. This functionality is generic
across all Xilinx SOCs that's why move it to common location to be used by
all Xilinx SOCs.

On zynq platform this is also fixing issue where U-Boot was placed to
locating which was reserved already which ends up with error message
"ERROR: reserving fdt memory region failed (addr=30000000 size=10000000
flags=4)" which is shown when bdinfo is called.

9c563e916c xilinx: Handle board_get_usable_ram_top(0) properly
board_get_usable_ram_top() was designed for getting the top most location
for U-Boot allocation that's why function itself supports via total_size
parameter to find out where the right location for U-Boot is.
But function itself is also reused by different (EFI) which is passing
total_size as 0 to find out where the usable ram top is. For this case
doesn't make sense (a waste time) to call any lmb functions.
That's why simply return gd->ram_top.

And gd->ram_top is filled already based on previous call for U-Boot iself.
The same solution is also used by stm32mp by commit 92b611e8b0 ("stm32mp:
correctly handle board_get_usable_ram_top(0)") and commit c8510e397f

398a74ae33 zynqmp: restore the jtag interface
When boot.bin is configured for secure boot the CSU will disable the
JTAG interface on all cases.

Some boards might rely on this interface for flashing to QSPI in which
case those systems might end up bricked during development.

This commit will restore the interface under CSU control

b86f43de0b xilinx: zynqmp: Add support for runtime dfu_alt_info setup
The main reason for this to be implemented is capsule update.
Two memories are supported and tested which is MMC FAT based and QSPI
based.

For creating capsule these commands are used:
./tools/mkeficapsule --raw spl/boot.bin --index 1 capsule1.bin
./tools/mkeficapsule --raw u-boot.itb --index 2 capsule2.bin

Then transfer to SD card where these commands run:
load mmc 0 10000000 capsule1.bin
efidebug capsule update -v 10000000
load mmc 0 10000000 capsule2.bin
efidebug capsule update -v 10000000

Depends on the boot device used are binaries loaded to qspi or mmc fat
partition.
Also multiboot register is handled to make sure that the same location(id)
is used as image which is upgraded.

Two locations are used by purpose for SPL flow. If only boot.bin is used
create only one capsule.

When U-Boot runs in EL2 there is no access to csu_base registers that's why
this has to be done via firmware interface to find out multi boot register

50918d0df5 xilinx: Return ENVL_NOWHERE instead of ENVL_UNKNOWN
The system refuses to boot without any environment, so return ENVL_NOWHERE when
there's nowhere to store the environment instead of ENVL_UNKNOWN.

This fixes that the board won't boot from eMMC when CONFIG_ENV_IS_IN_FAT is not
defined, for example. Similar for other combinations.

ce39ee28ec zynqmp: Do not place u-boot to reserved memory location
TF-A and SecureOS can allocate the part of DDR for self but U-Boot is not
handling this configuration that the part of memory is reserved and
shouldn't be used by U-Boot. That's why read all reserved memory locations
and don't use it.
The code was taken from commit 4a1b975dac ("board: stm32mp1: reserve
memory for OP-TEE in device tree") and commit 1419e5b516 ("stm32mp:
update MMU config before the relocation") which is used by stm32 and does
the job properly.
