Revert PCI config space writes on shutdown
This means all chipset enables etc. will be undone on shutdown. Reversible PCI config space writes now use rpci_write_*(). PCI config space writes which are one-shot (e.g. communication via config space) should continue to use the permanent pci_write_* variants. Extend the number of available register_shutdown slots to 32. Corresponding to flashrom svn r1232. Signed-off-by: Carl-Daniel Hailfinger <> Acked-by: Michael Karcher <>
