I think you need to set CONFIG_LOGICAL_CPUS=0 to disable the siblings. I
got it to compile by moving the nb_ function it can't find into the #endif
* AP 02 didn't start timeout:00000001
* AP 03 didn't start timeout:00000001
Begin FIDVID MSR 0xc0010071 0x30ae00a3 0x40034c40
FIDVID on BSP, APIC_id: 00
BSP fid = 10600
Wait for AP stage 1: ap_apicid = 1
fidvid_bsp_stage1: time out while reading from ap 01
Wait for AP stage 1: ap_apicid = 2
fidvid_bsp_stage1: time out while reading from ap 02
Wait for AP stage 1: ap_apicid = 3
It's still trying to start the APs.

If inl and outl are hanging, I would dump the routing registers and read the
device's IDs to see what's going wrong. I'm not very familiar with how the
fam10 code works, but dumping the routing registers should be mostly cut and
paste from the k8/util.c code.
