It's true that a few people have contacted me and asked for source code.
I think everyone has received a reply, although the reply may
not have been what the sender probably wanted it to be.
I'd like to make a general comment about "efiboot": You need to realize
that this is really a very, very thin layer of code. The only thing it
does is to act as a coreboot payload (through libpayload); build a
minimal UEFI-compliant HOB list and pass it to the DXE core. To do that,
you also need to load and start the DXE core from the Firmware Flash the
TianoCore build process creates.
I think anyone can do this and I believe the hardest part about this is
understanding UEFI and TianoCore. The good thing about that part is that
there is a lot of documentation plus I think you need to understand UEFI
(and the TianoCore implementation) anyways -- if you're seriously going
to use it.
Please don't take this as an angry comment about people sending me
emails. In fact, I'm always happy to hear from people interested in my
projects. Also, I'm more than happy to help with questions, but please
respect that I cannot release source code.
