2012-01-10MTRR: get physical address size from CPUIDSven Schnelle
The current code uses static values for the physical address size supported by a CPU. This isn't always the right value: I.e. on model_6[ef]x Core (2) Duo CPUs physical address size is 36, while Xeons from the same family have 38 bits, which results in invalid MTRR setup. Fix this by getting the right number from CPUID.

2011-01-19Now that the VIA code is run above 1Meg (like other boards), it shouldKevin O'Connor
cache that range instead of the first 1Meg. This reduces boot time by about 1 second on epia-cn. This patch also adds a MTRRphysMaskValid bit definition.

2010-11-13MTRR related improvements for AMD family 10h and family 0Fh systemsScott Duplichan
-- When building for UMA, reduce the limit for DRAM below 4GB from E0000000 to C0000000. This is needed to accomodate the UMA frame buffer. -- Correct problem where msr C0010010 bits 21 and 22 (MtrrTom2En and Tom2ForceMemTypeWB) are not set consistently across cores. -- Enable TOM2 only if DRAM is present above 4GB. -- Use AMD Tom2ForceMemTypeWB feature to avoid the need for variable MTRR ranges above 4GB. -- Add above4gb flag argument to function x86_setup_var_mtrrs. Clearing this flag causes x86_setup_var_mtrrs() to omit MTRR ranges for DRAM above 4GB. AMD systems use this option to conserve MTRRs. -- Northbridge.c change to deduct UMA memory from DRAM size reported by ram_resource. This corrects a problem where mtrr.c generates an unexpected variable MTRR range. -- Correct problem causing build failure when CONFIG_GFXUMA=1 and CONFIG_VAR_MTRR_HOLE=0. -- Reserve the UMA DRAM range for AMD K8 as is already done for AMD family 10h. Tested with mahogany on ECS A780G-GM with 2GB and 4GB. Tested with mahogany_fam10 on ECS A780G-GM with 2GB and 4GB.

2004-10-30- To reduce confuse rename the parts of linuxbios bios that run fromEric Biederman
ram linuxbios_ram instead of linuxbios_c and linuxbios_payload... - Reordered the linker sections so the LinuxBIOS fallback image can take more the 64KiB on x86 - ROM_IMAGE_SIZE now will work when it is specified as larger than 64KiB. - Tweaked the reset16.inc and reset16.lds to move the sanity check to see if everything will work. - Start using romcc's built in preprocessor (This will simplify header compiler checks) - Add helper functions for examining all of the resources - Remove debug strings from chip.h - Add llshell to src/arch/i386/llshell (Sometime later I can try it...) - Add the ability to catch exceptions on x86 - Add gdb_stub support to x86 - Removed old cpu options - Added an option so we can detect movnti support - Remove some duplicate definitions from pci_ids.h - Remove the 64bit resource code in amdk8/northbridge.c in preparation for making it generic - Minor romcc bug fixes git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1727 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
