4.11_branch is now completely gone. kfsn4-dre is using it.
if it doesn't build, i'll just set kfs to release=n. that
board never worked properly anyway and isn't officially
supported by 15h.org either.

otherwise, the recent fix to coreboot builds breaks
seabios builds.

lbmk should be stable now.

aka "Mike's coreboot"

libreboot recently improved its multi-tree design to
allow specifying git repository links per-tree instead
of just per-project. this means i can now use the 15h
fork quite easily, on fam15h boards. this fork uses
AMD's AGESA source code instead of raptor engineering's
code. the modified AGESA code is compatible with a lot
more memory modules, and can support higher amounts of
memory. it's generally more reliable.

the only submodule they changed was the blobs one,
but the only commits they add are things i don't
need. they add commits that violate copyright, e.g.
distributing AST2500 VGA ROM without permission.
thus, i do not use their blobs repo. i use the
upstream coreboot one, which has what we need.

since i don't use the VGA ROM in libreboot, it's
fine. therefore, the submodule config is currently
the same as the old 4.11 tree.

they were missing two of my build fixes. they have
added some of their own as well.

note that there are two boards for kgpe-d16 and d8
here: the raptor one, and the agesa one. we are using
the agesa one.

kfnsn4-dre still uses the old tree.

i'm going to add the 15h.org fork and name it
fam15h

only do if config=y. this reintroduces a hack that
i accidentally removed in the recent redesign.

grub has been changed to noconfig=y, and the files
for memdisk are now source from config/data/grub
