Now bimini can boot linux to login.
Note:
1. bimini_fam10/Kconfig: Set GENERATE_MP_TABLE in Kconfig. This will make sure the
smp_write_config_table will run. Then intr_data will be written
into 0xC00/0xC01.
2. bootblock: Use PCI_DEV(0, 0x14, 3) instead of
pci_locate_device(PCI_ID(PCI_VENDOR_ID_ATI, PCI_DEVICE_ID_ATI_SB800_LPC), 0).
The pci_locate_device will cause the system crash.
3. fadt.c: Change fadt revision to 1. 3 will cause the linux hang. Why?
4. early_setup.c: pmio 0x65 has change its meaning.
