[LinuxBIOS] [patch] flashrom: add support for Asus P5A

[Luc Verhaegen]

Here's the chip_enable code for the ALI M1533 and the board_enable for 
the Asus P5A, an ALI M1541+M1533 socket 7 motherboard.

It's quite nasty:
It does an SMBUS read/write to a yet unidentified device, i think it is 
the superio, but i'm not sure.
The Asus P5A also seriously messes up pci-ids, there is nothing 
dependable there, so people who want to use flashrom on this board 
should use -m asus:p5a

but it works :)

This is a board i own myself and this has been tested successfully.
