RE: Board hangs after soft_reset() in auto.c

[YhLu]

That only used by auto.c (in_conherent.c)

And it is ok to be overlapped in c parts. ( hardwaremain)?

To do that, only let cpu can see different BUS in auto.c stage.

Can this cause configuration regions overlap with each other during
device enumeration? In amdk8_scan_chains() the subordinate/limit field of
current register is set to 0xff before hypertransport_scan_chain(),
while other following registers are not touched yet, so they overlay with
current register?
