[coreboot] ASUS M4A77TD-PRO. First step: buy spare flash chips...

[Qing Pei Wang]

hi jiang,
  it is impossible to make the developers to port all of the
mainboard.Actually,
we take things as different chipset/cpu. If you found that the
chipset/cpu/superio of
one mainboard has already been supported, you can take a try to use
coreboot.
