Author: rminnich Date: 2008-08-18 00:18:09 +0200 (Mon, 18 Aug 2008) New Revision: 781
Modified: coreboot-v3/arch/x86/Kconfig coreboot-v3/include/arch/x86/amd/k8/k8.h coreboot-v3/mainboard/amd/Kconfig coreboot-v3/northbridge/amd/k8/common.c coreboot-v3/northbridge/amd/k8/cpu.c coreboot-v3/northbridge/amd/k8/domain.c coreboot-v3/northbridge/amd/k8/pci.c Log: We're much closer.
Added a stepping enum to k8.h. This will allow us to do things like this: if (cpu_stepping(node) < E0)
and so on instead of is_cpu_pre_e0_in_bsp or whatever it is.
Added and fixed Kconfig variables.
Broke out northbridge by function, so we can see what goes with what.
This tree still builds a working DBE62 coreboot that boots a kernel; no harm done to existing ports.
