r792 - in coreboot-v3: arch/x86 include include/arch/x86/amd/k8 mainboard/amd mainboard/amd/serengeti northbridge/amd/geodelx northbridge/amd/k8
Author: rminnich Date: 2008-08-21 18:04:41 +0200 (Thu, 21 Aug 2008) New Revision: 792
Added: coreboot-v3/include/spd_ddr2.h coreboot-v3/mainboard/amd/serengeti/mainboard.h Modified: coreboot-v3/arch/x86/Makefile coreboot-v3/include/arch/x86/amd/k8/k8.h coreboot-v3/mainboard/amd/Kconfig coreboot-v3/northbridge/amd/geodelx/raminit.c coreboot-v3/northbridge/amd/k8/raminit.c Log: Add ddr2 defines.
Continue to upgrade northbridge for k8.
Add a new standard include (which is optional on some chipsets), mainboard.h, which will define important mainboard constants that 1. do not belong in dts 2. do not belong in Kconfig 3. are so tightly tied down to the mainboard they should probably not be visible, i.e. the value of the variable is defined by artwork on the mainboard, such as the socket type.
This file resolves the long-standing question of where certain mainboard-dependent, compile-time control variables belong. We've not resolved this issue in two years so here's how we're going to do it. The first use of this is in the definition of CPU_SOCKET_TYPE, needed by the northbridge code.
These changes do not affect existing Geode builds (tested on DBE62).
