super experimentally dysfunctional port, in libreboot.
untested, guaranteed to *not* work, so you should *not*
install this, unless you want a royal pain in your a**.
thank you.

NOTE: the ifd.bin and gbe.bin are fake.
just zeroes
TODO: put real ones there
TODO: support scanning for these in blobutil

NOTE: EC not auto-downloaded yet, and not specified in the
coreboot configuration file.
TODO: important!
(add support for this to blobutil)

SUPER DUPER NON-FUNCTIONAL AND BROKEN, IN SEVERAL WAYS.

for example, files being downloaded have nothing to do
with the ME; they are merely compressed, and contain many
files in addition to it

rename board configs, and add to sources file the
t530/w530 boards

in some situations, the files weren't being downloaded

New x230edp_12mb target uses the
https://review.coreboot.org/c/coreboot/+/28950 patchset to add an
X230_EDP target to the default coreboot branch.
Consequently the "fhd" coreboot branch is no longer needed and has
been safely removed.

osboot is now part of libreboot, and will soon shut down.
libreboot now conforms to osboot policy.
