Neal Frager 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.

******************************************
Xilinx ZCU102 / ZCU106 boards - ZynqMP SoC
******************************************

This document describes the Buildroot support for the ZCU102 and
ZCU106 boards by Xilinx, based on the Zynq UltraScale+ MPSoC (aka
ZynqMP).  It has been tested with the ZCU102 and ZCU106 production
boards.

Evaluation board features can be found here with the links below.

ZCU102:

ZCU106:

How to build it
===============

Configure Buildroot:

    $ make zynqmp_zcu106_defconfig

Compile everything and build the rootfs image:

    $ make

Result of the build
-------------------

After building, you should get a tree like this:

    output/images/
    +-- atf-uboot.ub
    +-- bl31.bin
    +-- boot.bin
    +-- boot.vfat
    +-- Image
    +-- rootfs.ext2
    +-- rootfs.ext4 -> rootfs.ext2
    +-- sdcard.img
    +-- system.dtb -> zynqmp-zcu106-revA.dtb
    +-- u-boot.itb
    `-- zynqmp-zcu106-revA.dtb

How to write the SD card
========================

WARNING! This will destroy all the card content. Use with care!

The sdcard.img file is a complete bootable image ready to be written
on the boot medium. To install it, simply copy the image to an SD
card:

    # dd if=output/images/sdcard.img of=/dev/sdX

Where 'sdX' is the device node of the SD.

Eject the SD card, insert it in the board, and power it up.
