Eric,

Without hard_reset, s2885 is ok now.

In the k8/cpufixup.c need compare mmio_basek and 0x3f0000 and then assign
that to TOM.

Regards

YH

Eric,

If I disable the hard_reset, it can enumerate from link2 to link0. And the
8131 on link2 and 8151 on link0 all show out.

Maybe you can add MACRO to control reverse scan for AMKK8 northbridge. (
link2 then link0)

But it continues to reboot.

Eric,

In the hypertransport_scan_chain, if the hard_reset is needed, it may
produce problem.

Hard_reset call 8111 LPC (B1, D4, F0) reg 0x47 to trigger Reset.

But it is called before pci_scan_bus. At that time the 8111 LPC is still
unkown.

Regards

YH

I still have problems for s2885.

Amdk8_scan_bus for MC0 only from link0 to link2.  link0 is connected to 8151
and link2 is connected to 8131.

Then it reboot again and agin.

After I reverse the scan from link2 to link0. It can scan out 8131 and 8111
but hung after "HyperT reset needed" is printed. Maybe the reset.c that I
move from hdama got some problems.

YH.
