Right, README.sources refers to the sources used to generate the
binaries in a released BSP e.g. the release tarballs on the Yocto BSP
Downloads page(s).

No. the README.sources indicate what was actually used to build the
images, which can and do contain much more than what is specified by the
recipes in the BSP layer.

So README.sources is meaningless if there are no binaries in /binary,
and the layer itself may have no /binary directory or README.sources
until a tarball is generated for release, which generation might be done
by the release process instead.

Again, this all refers to released BSPs, and if e.g. meta-fri2 doesn't
have these in the meta-intel git repo, any meta-fri2 released BSP
certainly does.
