  - DP audio PLL should use the RPLL (0x3)
  - DP system time clock PLL should use RPLL (0x3)

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
("stm32mp: Fix board_get_usable_ram_top()").

The commit 0dba45864b ("arm: Init the debug UART") calls
debug_uart_init() from crt0.S but it won't work because SOC is not

psu_init() via new psu_uboot_init() earlier before the first access to UART
in SPL. In full U-Boot call psu_uboot_init() only when

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.

3d238435b2 xilinx: zynqmp: use zynqmp_mmio_read() in multi_boot()
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
value. Till now this function is called only from SPL in EL3.

7e5f460ec4 global: Convert simple_strtoul() with hex to hextoul()
It is a pain to have to specify the value 16 in each call. Add a new

Add a proper comment to simple_strtoul() while we are here.

The SPL can also be compiled with sysreset drivers just fine, so
update the condition to cater for that option.

do_reset() if sysreset is enabled").

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.

a70bdafd67 mmc: zynq_sdhci: Split set_tapdelay function to in and out
Split arasan_zynqmp_set_tapdelay() to handle input and output tapdelays
separately. This is required to handle zero values for ITAP and OTAP
values. If we dont split, we will have to remove the if() in the
function, which makes ITAP values to be overwritten when OTAP values are
called to set and vice-versa.

Restrict tap_delay value calculated to max allowed 8 bits for ITAP and 6
bits for OTAP for ZynqMP.

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.
