The two files would need to be combined, plus the upstream files are in a different format to the Buildroot hash files.

You don't have to use the content of these files directly. But when upstream provides hashes we usually use them in .hash, and mention their source in a comment. See for example package/btrfs-progs/btrfs-progs.hash.

PATCH 3/3 package/linux-headers: add support for custom headers.

In reply to Mark Corbin

Add support for building toolchains against custom headers. Allows the selection of a manual version, custom tarball or custom git repository for the kernel headers. This enables toolchains to be built against custom kernel headers without having to build a full kernel.

This is particularly useful for new architectures, such as RISC-V where updated kernel headers may not have made it into the mainline kernel yet.
