Hello,

The title should have been:

	configs/arm_juno: add support for Juno r2

This part is not needed, as it only repeats the commit title with no
other additional information.

I guess you meant r2 here.

Applied with those issues fixed.

Thanks!

No, you should have kept using
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_X_Y, since this tells Buildroot
to use the kernel sources specified below for the kernel headers used
to build the toolchain.

I've already applied, but when using such an official release, using
the tarball would be much more download efficient.

Applied with the kernel headers change. Thanks!
