2b564a8ccf configs/zynqmp_kria_kv260_defconfig: fix pmufw sw reset
This patch will solve the problem of the pmufw built by the
zynqmp-pmufw-builder where soft resets crash for the kv260.
Details of the issue can be found here:

https://lore.kernel.org/buildroot/87ilqccu3k.fsf@dell.be.48ers.dk/

Please note that this is a temporary solution as the kv260
pmufw is not yet available on the Xilinx github. This is expected
in the coming months.  The nealfrager github uses the same
licensing terms as the Xilinx github regarding the distribution of
zynqmp pmufw binary files.

da7b674d91 configs/zynqmp_kria_xxx_defconfig: uboot dp pll patch
This patch fixes the DP audio and video PLL configurations for the zynqmp-sm-k26-revA som.
It needs to be applied for both the kv260 and kr260 starter kits.

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.

This patch was build and run tested on a zynqmp-kria-kv260 target board.

Upstream-Status: submitted (https://lore.kernel.org/all/fa7e9abc419c9d7648405d1c62367dbe701d09b8.1652709736.git.michal.simek@amd.com/)
This patch will be removed from buildroot in a future release when no longer necessary.

of uart0 for the Kria KV260 Starter Kit.

f67720baa3 configs/zynqmp_kria_kv260_defconfig: fix to u-boot.itb generation
This patch is a temporary fix for the kv260 u-boot.itb generation
until a proper fix has been implemented within u-boot.

The problem is u-boot can only be configured to use the kria k26
som dts configuration at build time, and the kv260 carrier board
overlay is missing from the build.  Without this, all of the carrier
board drivers are missing.

This patch will be removed from buildroot once u-boot can build a
correct u-boot.itb for the kria kv260 starter kit including the
carrier board overlay and corresponding drivers:

9bba9f1062 configs/zynqmp_kria_kv260_defconfig: add parameters to generate extlinux.conf
This patch enables the zynqmp_kria_kv260_defconfig to auto-generate the
extlinux.conf file.

The board/zynqmp/kria/extlinux.conf and board/zynqmp/kria/post-build.sh have
been removed as they are no longer necessary.

b73f5c32af add configs/zynqmp_kria_kv260_defconfig
This patch adds support for Xilinx Kria KV260 starter kit.

KV260 features can be found here:
https://www.xilinx.com/products/boards-and-kits/kv260.html

While the Kria SOM is based on a ZynqMP SoC, there are some key
boot config differences from the other ZynqMP evaluation boards.

1. There are no boot switches on Kria SOMs. The boot mode is thus
hard configured for QSPI flash. A pre-programmed boot.bin comes
with every Starter Kit. U-Boot can then find the Linux kernel and
file system on the SD card.

Optional instructions for updating the boot.bin in the QSPI flash
can be found in the readme.txt file and the link below.

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1641152513/Kria+K26+SOM

2. Kria SOMs use UART1 for the console instead of UART0. For this
reason, Kria Starter Kits will use a separate extlinux.conf file
from other ZynqMP evaluation boards.
