board: add support for ARM Juno r1 Development Board
PATCH v3 1/1 board: add support for ARM Juno r1 Development Board
The Juno r1 ARM Development Platform (ADP) is a software development platform for ARMv8-A, it includes the Juno r1 Versatile Express board and an ARMv8-A reference software port available through Linaro.
Remark: The kernel' arm64 defconfig lacks a considerable amount of configuration items regarding the Juno r1 board, and that is the reason of this custom kernel configuration file.

Thanks for this new version!

Remark: The kernel' arm64 defconfig lacks a considerable amount of configuration items regarding the Juno r1 board, and that is the reason of this custom kernel configuration file.

This is wrong: you shouldn't tell users to look into output/build/. All useful output should be in output/images/.
Also, these instructions are not very interesting: you should explain how to actually "install" the kernel image and Device Tree blob.
Please look at other readme.txt in Buildroot to see good examples. I think board/raspberrypi2/readme.txt is a good example.
Thanks,
Thomas
