[coreboot] 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
