Neal Frager 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.

******************************************
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.

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.
