Add support for MA785GM-US2H
This patch adds coreboot support for the
GIGABYTE MA785GM-US2H board.
This port now removes all dead code in
the previous patch set, and also boots Fedora 16
on x86_64 (Phenom II X4 955 BE)
On-board audio causes spurious interrupts and
the kernel gets stuck in an infinite loop.
AtomBIOS on RadeonHD video cards does not function
and causes another infinite loop. radeon.modeset=0
must be set. acpi=off must also be set.
With those kernel command line options set,
Fedora 16 makes it to the login screen. USB
mouse and keyboard don't work though. several
USB error codes on boot-up. PS/2 should.
