Drom.c3 * PCI ROM access routines
16 * pci_enable_rom - enable ROM decoding for a PCI device
19 * Enable ROM decoding on @dev. This involves simply turning on the last
20 * bit of the PCI ROM BAR. Note that some cards may share address decoders
21 * between the ROM and other resources, so enabling it may disable access
38 * Ideally pci_update_resource() would update the ROM BAR address, in pci_enable_rom()
40 * devices have buggy ROM BARs that read as zero when disabled. in pci_enable_rom()
52 * pci_disable_rom - disable ROM decoding for a PCI device
55 * Disable ROM decoding on a PCI device by turning off the last bit in the
56 * ROM BAR.
