[Linux-fbdev-devel] New kernel API for ROMs

[Jon S. <jon...@ya...>]

This patch provides a new kernel API for access ROMs from device
drivers. If you're working on a driver that uses the ROM (most video
drivers) please give this patch a try and send some feedback/bugs.

pci_map_rom() - map the rom and provide virtual address, transparently
return shadow/copy if needed. Normal drivers call this

pci_map_rom_copy() - same as pci_map_rom except the ROM will copied,
future reads of ROM will use copy. Hardware with minimal decoding calls
use this

pci_unmap_rom() - release the ioremap if there is one

The ROMs also appear in sysfs and you can use hexdump to see them.

If the Radeon ROM is all FFFF. Load a radeon device driver and it will
appear. Radeon cards have a bug that loading the driver will fix.
