23 * It does not matter where we put the SMBus I/O base, as long as we
24 * keep it consistent and don't interfere with other devices. Stage2
25 * will relocate this anyways.
26 * Our solution is to have SMB initialization move the I/O to SMBUS_IO_BASE
27 * again. But handling static BARs is a generic problem that should be
28 * solved in the device allocator.
