Good to head it isn't dead.

Thanks, I'll have a look (might take some time though as I'll go vanish
into my summer vacation soon).

Yep, tables are most important to get rid of hardware dependencies.

Right now corebootPkg/Library/AcpiTimerLib tries to poke directly at the
pmtimer of the piix4 southbridge.  And when running on other hardware it
traps into an assert.  Would be better to get the pmtimer address by
parsing the FADT like seabios does.

Native GOP driver only matters when running without CSM, with CSM
present it wouldn't be used anyway.

Doesn't build:

"GenFw" -e SEC -o
GenFw: ERROR 3000: Invalid
  Unsupported section alignment.
make: ***
Error 2

Note this is with the coreboot patches rebased, not your branch.
I think it comes from some edk2 changes.  Might also be I did something
wrong while rebasing ...
