The Linux environment for all boards using the Canaan Kendryte K210 SoC
can be built with the same process, using configurations that differ
only by the device tree used for the build. This patch add the
shared configurations, rootfs overlay and scripts used for all
K210-based boards.
Since the K210 SoC only has 8 MB of SRAM, a special busybox
configuration and rootfs overlay are added to save memory at runtime:
* For configurations using direct kernel boot (no boot loader), the
default busybox configuration busybox-minimal.config is modified
using the fragment file board/canaan/k210-soc/busybox-tiny.config.
This reduces the size of the busybox executable to save memory when
executing shell commands.
* Busybox init system is not used and a special init scripts is provided
using the rootfs_overlay root file system overlay. This init script
simply mounts devtmpfs, /proc and /sys, and exec an interactive shell
after printing a logo. This avoids (1) boot failures due to large
memory allocations by the regular busybox init system (these
allocations fail on the K210 for lack of enough memory) and avoids
(2) keeping the init process sleeping in the background (wasted
memory).
The board/canaan/k210-soc/busybox-tiny.config and the rootfs overlay
files in board/canaan/k210-soc/rootfs_overlay are used for all Canaan
K210 SoC based boards.
For board configurations booting using the U-Boot boot loader, a common
set of linux kernel configuration parameters is provided by the file
board/canaan/k210-soc/linux-sdcard.config. In addition, the post build
script board/canaan/k210-soc/post-build.sh file and U-Boot image
generation configuration file board/canaan/k210-soc/genimage.cfg are
provided. The post-build script creates a generic "k210.dtb" symlink to
the compiled device tree file for the target board. This symlink is used
by the genimage.cfg configuration, making this file common for all
boards.

The genimage.cfg modified by this commit used the partition-type-uuid
c12a7328-f81f-11d2-ba4b-00a0c93ec93b, which identifies the EFI System
Partition, for a partition that isn't the EFI System Partition, but
just a regular FAT partition, for which GUID
ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 is more appropriate.
So we switch these to use partition-type-uuid = F, as it makes more
sense.
Please note that this commit introduces a difference in the resulting
output, as those partitions will now have a different GUID.

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.

This patch is a temporary fix for the kv260 u-boot.itb generation

overlay is missing from the build. Without this, all of the carrier

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.
