[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?

Anyone have any contact information for who reported this to begin with? 
Because that is the only thing that's standing in the way of adding 
chipset/board support for this hw.

I fear that this was an irc discussion somewhere, and here the lack of 
logging is seriously hampering progress.

Could look at wiki history to see who added it to the wiki at least.

Mh - if you send a patch I think it'll get applied. Do you know the
PCI ids?

Ah, right; result: uwe added this late december, just a month before i 
sent my original email. "Supported mainboards:  ASUS A7N8X-E Deluxe does 
_not_ work with flashrom."

I'm not sure whether i have a good irclog from that time at hand, to 
find out what happened there.

Yeah, i could dig this out again.

Thanks,
