The following patch implements Opteron Fam 10 rev D (aka Istanbul)
support for coreboot. I have not updated MAX_CPUS for all fam10 mainboards, but it might make sense to multiply those by 1.5. Signed-off-by: Arne Georg Gleditsch <arne.gleditsch@numascale.com> I assume the line pci_write_config32(NODE_PCI(nodeid, 0), 0x168, dword); should be put outside the loop. Everything seems to be fine. I don't have Istanbul to test. I have read every changes and they all look good. Acked-by: Zheng Bao <zheng.bao@amd.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5200 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
