AMD A76M chipset?

[Carl-Daniel Hailfinger]

Hi,

HP and other laptop vendors claim to use an AMD A76M chipset in some of
their machines. I have been unable to find any info about (or even
confirm the existence of) the A76M on the AMD website or any other
reliable source.
https://en.wikipedia.org/wiki/Comparison_of_AMD_chipsets is also silent,
but the numbers there suggest the A76M might be a Bolton chipset.

Does anyone know if there are public docs for the A76M (possibly under
another name), and how feasible it is to drive it with current public
(or to-be-released) AGESA?

Regards,
Carl-Daniel

Hi all,

I'm CCing Bruce, maybe he knows.

According to random googled page:
> The A76M FCH is an upgraded A70M FCH, or better yet A76M = Bolton M3 and A70M =

Hudson M3.
> Does anyone know if there are public docs for the A76M (possibly under

Anyway, how it looks with AMD/AGESA story?

I think bolton should be very similar to Hudson, and googling for A88X its
revision number starts at 16h (the hudson had 11-14h)

There is a good chance that Bolton will somewhat work with current hudson I
think - even PCI IDs match.

Maybe we can try first to support some FM2+ board with bolton and see how it
goes. I'm all for that considering the effort I put into the FCH/Trinity AGESA
it would be a shame if it is wasted just with a single board ;)

Possible candidates:
Looks quite new (seems released this year)

ASUS A88X-PLUS  (Lunched 09/11/2013)
ASUS A88X-PRO (Lunched in January?)
A88XM-A (Lunched 07/29/2013)

Most promising:
ASUS A78M-E - AMD A78 (very new, microITX, cheap, ITE sio)

Very similar:
ASUS A78M-A (but more dimm slots, supported SIO, launched February?)

Is here someone who wants to work on this perhaps together with me? (of course
donations welcome ;) I will buy some / work on that only if someone else buys it
too.

Thanks

I've started porting coreboot to the ASROCK FM2A88M-HD+ (A88X chipset) 
and have nearly finished the code for the SIO chip used on that board 
(NCT6776). Will upload that soon, but still have to do some cleanup and 
verify some stuff with the datasheet.

If you'd like to help me with that board, I'd donate you a FM2A88M-HD+. 
But until august I sadly only have time for coreboot-related stuff on 
the weekends.

The only downside of that board is that the PCIe x1 slot is located next 
to the PCIe x16 slot; so if you want to use a fast graphics card the 
only PCIe x1 slot gets blocked mechanically.

Not on your list but I was considering the ASRock FM2A88X-ITX+
