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;
}
