Recent AMD chipsets

[Niels Ole Salscheider]

Hello,

are there any plans to port coreboot to a recent AMD chipset like 780G / 
SB700? I would like to see coreboot running on the ASUS M3A-H/HDMI.

I am not very experienced in low-level programming but I am willing to learn 
and to spend some time to port coreboot to that chipset.
How far is the progress of coreboot v3? Is it a good idea to use that version 
or is it better to use coreboot v2 and port it to v3 as soon as it is stable?

The flash chip on the ASUS M3A-H/HDMI is a SPI chip like the one that can be 
found on the GIGABYTE GA-M57SLI-S4. There is a second unused position, too.
Are there any limitations on the chips that can be used or can I use any of 
the supported spi chips (like the MX25L3205)?

Kind regards

Ole

Hi All,

I  have such question too. I have some borad using Intel 5000 MCH and ESB2
southbridge, I have check coreboot supported chipset list, I have not see
any version of coreboot support this board. I'd like to try  let coreboot
run at this board.

I can't decide which version of coreboot to use, And I'm a newcomer, I don't
know what's the major difference between V2 and V3.

Best Regards.

Qin.

The AMD 690/600 is in the works.

Start with V2, then it can be moved into V3.

Depends on the southbridge as far as how large the spi device may be.

That sounds great and I think that it won't be to difficult to move to AMD 
780G / SB700, will it?
Nevertheless, I cannot find any code for AMD 690 / SB600 in SVN - is it 
already there?

I think that we need further information concerning irq routing (I think I 
have to ask ASUS for it) as well as the southbridge (like the addresses 
passed to pci_write_config32, right? I have to ask AMD for that).
Do I need further information?

What is the difference between v2 and v3 / will it be difficult to move it?

The chip found on my mainboard is a MX25L8005 with 8MBit. Where can I buy a 
MX25L8005 or a larger chip (in Germay)? I have found 8MBit and 16Mbit spi 
chips on http://www.bios-fix.de (13,54€ + 2,21€) but I cannot find the 
MX25L3205.

Kind regards
