Add OPROM mapping support to coreboot
This allows to add a PCI ID mapping function for option roms so that the same option rom can be used for a series of devices / PCI IDs. Intel and AMD often use the same option rom for a number of PCI devices with differend IDs. A function to implement such a mapping could look like this (or anything else appropriate): /* some vga option roms are used for several chipsets but they only have one * PCI ID in their header. If we encounter such an option rom, we need to do * the mapping ourselfes */ u32 map_oprom_vendev(u32 vendev) { u32 new_vendev=vendev; switch(vendev) { case 0xa0118086: new_vendev=0xa0018086; break; } return new_vendev; } Change-Id: I1be7fe113b895075d43ea48fe706b039cef136d2 Reviewed-on: http://review.coreboot.org/573 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
