Old operating systems would like to have a rev1 (ACPI 1.0) FADT, but
new operating systems would like to have rev3 (ACPI 2.0).
Since old operating systems do not know about XSDTs, the
solution is to point the RSDT to a v1 FADT and the XSDT to a
rev3 FADT.


Paolo Bonzini (2):
  seabios: build RSDT from XSDT
  seabios: create rev1 FADT in compatibility RSDT
