Revert MMIO space writes on shutdown as needed
Reversible MMIO space writes now use rmmio_write*(). Reversible PCI MMIO space writes now use pci_rmmio_write*(). If a MMIO value needs to be queued for restore without writing it, use rmmio_val*(). MMIO space writes which are one-shot (e.g. communication with some chip) should continue to use the permanent mmio_write* variants. Corresponding to flashrom svn r1292. Signed-off-by: Carl-Daniel Hailfinger <> David tested it successfully on some NM10/ICH7 platforms which switch between SPI and LPC targets (x86 BIOS ROM vs. EC firmware ROM).
