[coreboot] [flashrom] Asus A7N8X-E Support.

[Luc Verhaegen]

With the discussion of the board_enables table, i ended up looking at 
the flashrom page on coreboot.org and spotted a bunch of boards that are 
known to not work.

The first one i looked at was the aforementioned and this here is what 
is needed for the flash enable of that board.

{
	uint8_t tmp;

	pci_write_byte(dev, 0x92, 0);

	tmp = pci_read_byte(dev, 0x6D);
	tmp |= 0x01;
	pci_write_byte(dev, 0x6D, tmp);
}	

While it seems that the second operation seems to match both ck804 and 
mcp55 chip enables, this is not true. The device used is 0:01.0 (ISA 
bridge) and not 0:01.1 (SMB controller).

I googled, but could not find a report to the coreboot (or linuxbios) 
list of this board being tested. Does anyone remember who reported this 
as broken?
