6be41ea4e6 arm64: zynqmp: zynqmp-sm-k26-revA: Fix DP PLL configuration
This patch fixes the DP audio and video PLL configurations for the zynqmp-sm-k26-revA som.

The Linux DP driver expects the DP to be using the following PLL config:
  - DP video PLL should use the VPLL (0x0)
  - DP audio PLL should use the RPLL (0x3)
  - DP system time clock PLL should use RPLL (0x3)

Register 0xFD1A0070 configures the DP video PLL.
Register 0xFD1A0074 configures the DP audio PLL.
Register 0xFD1A007C configures the DP system time clock PLL.

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
CONFIG_ZYNQMP_PSU_INIT_ENABLED is enabled.

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.

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.

K26 has EMMC and SD and default 0 is not working when system is booting out
of SD which is controller 1. Add controller autodetection via
mmc_get_env_dev(). The same code is used for distro_boot selection done in
board_late_init(). bootseq variable can't be reused because this is called
so late.

ef1be3e364 xilinx: zynqmp: Add usb dfu/thor distro boot support
In usb boot mode distro boot should select usb device as primary boot
device instead of usb host. So make usb dfu as primary boot device. But do
not list it in boot_targets as fallback option because it is not classic
mode for booting. Using 60s timeout by default should be enough time for
dfu-utils to start transaction. In case none needs this please change
timeout value in the command or disable CONFIG_DFU_TIMEOUT.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;
    type argtype;
    @@
    - reset_cpu(argtype argname)
    + reset_cpu(void)
    { ... }
