[coreboot] run away pci scan

[Marc Jones]

I'm working with amd/mahogany_fam10 mainboard and having problems in
ramstage. It is going through pci device scanning when it starts
finding the same devices again and malloc memory until it dies. It
also looks like it never goes down a bridge, always staying on bus0.
The problem starts at CPU: APIC: 03, it starts scanning bus0 again.

Enumerating buses...
Show all devs...Before Device Enumeration.
Root Device: enabled 1, 0 resources
APIC_CLUSTER: 0: enabled 1, 0 resources
APIC: 00: enabled 1, 0 resources
PCI_DOMAIN: 0000: enabled 1, 0 resources

... normal device init happens.....

CPU: APIC: 00 enabled
malloc Enter, size 1092, free_mem_ptr 00270000
malloc 00270000
CPU: APIC: 01 enabled
malloc Enter, size 1092, free_mem_ptr 00270444
malloc 00270444
CPU: APIC: 02 enabled
malloc Enter, size 1092, free_mem_ptr 00270888
malloc 00270888
CPU: APIC: 03 enabled
PCI_DOMAIN: 0000 scanning...


Anyone have  thoughts on what is happening here? Attached complete serial log.

Thanks!
Marc
