This patchset adds basic support for Andes's nds32 ISA
and nds32 family's CPU IP based on ae3xx platform.
The board is entirely supported since Linux 4.17.

It is not clear what you want to support here. You're talking about a "Buildroot generated toolchain", so I would expect that one can build a toolchain with Buildroot for nds32. But: - You have selected BR2_ARCH_HAS_NO_TOOLCHAIN_BUILDROOT, which prevents building a toolchain with Buildroot - I don't see any upstream support for nds32 in glibc.

Also, for our defconfigs, we require a readme.txt file, in board/andes/ae3xx/readme.txt, which briefly says how to use the defconfig. See other readme.txt files in board/.

This autobuild configuration is using an external toolchain, so it is not at all testing "internal toolchain with glibc". Also, are you ok with analyzing the build failures that will be reported by our autobuilders for the nds32 architecture, investigate them and provide fixes ? Thanks!
