Binutils 2.39 now warns when a segment has RXW permissions: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=ba951afb99912da01a6e8434126b8fac7aa75107 This causes the following build error: aarch64-buildroot-linux-gnu-ld: bl31.elf has a LOAD segment with RWX permissions. This patch applies the upstream boot/arm-trusted-firmware/v2.6 patch already included with buildroot to solve the problem.

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.

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.
