[commit] r5199 - trunk/src/southbridge/amd/sb600

New Revision: 5199
URL: http://tracker.coreboot.org/trac/coreboot/changeset/5199

Log:
sb600 has problems with the virtual wire mode setup in setup_ioapic(). It causes problems when interrupts are enabled (specifically timer).
Previously the sb600 setup was equivalent to clear_ioapic(), so that is what we will do for now.
