 `Commit 1f7d3c5672ec90f8d71907b1a07c8a87fa461047 "AMD-8111: Add
 TINY_BOOTBLOCK support."` breaks coreboot on Tyan S2885 and probably other
 K8 boards because the bootblock doesn't enumerate the (noncoherent) HT
 chain before trying to write to the ROM Decode Control Register on the
 AMD-8111 I/O Hub.

I think a BOOTBLOCK_NORTHBRIDGE_INIT analogous to amdfam10 should fix
 this.
