[PATCH] PCI: reverse pci config space restore order
According to Intel ICH spec, there are several rules that Base Address
should be programmed before IOSE (PCICMD register ) enabled.
For example ICH7:
12.1.3 SATA : the base address register for the bus master register
should be programmed before this bit is set.
11.1.3: PCICMD (USB): The base address register for USB should be
programmed before this bit is set.
....
To make sure kernel code follow this rule , and prevent unnecessary
confusion. I proposal this patch.
