Re: [coreboot] PCIe devices not enabled on amd/persimmon

[Andy Sharp]

I can now confirm this.  Despite the hardware documentation for the board
clearly showing the PCIe slot as being on the south bridge, it is not.  I
got a PCIe extension cable this morning that would actually fit, and the
device plugged in shows to be a child of device 6.0, which is the third
PCIe port on the northbridge/cpu.  Sigh.

This is a big bummer for me, as my employer has a design based on
persimmon, except all the devices are on the southbridge instead of the
northbridge, and we are struggling to get coreboot to see them and yet not
hang.  I know it can be done, because the BIOS does enable all the devices
and boots, so it's just coreboot that isn't quite getting it right.

Cheers,

a
