2012-04-27SMM: unify mainboard APM command handlersStefan Reinauer
rename from mainboard_apm_cnt to mainboard_smi_apmc to match the function naming scheme of the other handlers. Add prototype for mainboard_smi_sleep (mainboard specific S3 sleep handlers in SMM) that is required by Sandybridge.

Also, delete the unused struct device declaration and move the struct bus declaration to where it's used.

2012-04-26Revamp Intel microcode update codeStefan Reinauer
- add GPLv2 + copyright header after talking to Ron - "bits" in struct microcode served no real purpose but getting its address taken. Hence drop it - use asm volatile instead of __asm__ volatile - drop superfluous wrmsr (that seems to be harmless but is still wrong) in read_microcode_rev - use u32 instead of unsigned int where appropriate - make code usable both in bootblock and in ramstage - drop ROMCC style print_debug statements - drop microcode update copy in Sandybridge bootblock Change-Id: Iec4d5c7bfac210194caf577e8d72446e6dfb4b86 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/928 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-04-04Add support to run SMM handler in TSEG instead of ASEGStefan Reinauer
Traditionally coreboot's SMM handler runs in ASEG (0xa0000), "behind" the graphics memory. This approach has two issues: - It limits the possible size of the SMM handler (and the number of CPUs supported in a system) - It's not considered a supported path anymore in newer CPUs.

2012-04-03Add support for Intel Turbo Boost featureStefan Reinauer
From wikipedia: Intel Turbo Boost is a technology implemented by Intel in certain versions of their Nehalem- and Sandy Bridge-based CPUs, including Core i5 and Core i7 that enables the processor to run above its base operating frequency via dynamic control of the CPU's "clock rate". It is activated when the operating system requests the highest performance state of the processor.

The cbmem console structure and car global data are put in their own section, with the cbmem console coming after the global data. These areas are linked to be where CAR is available and at the very bottom of the stack. There is one shortcoming of this change: The section created by this change needs to be stripped out by the Makefile since leaving it in confuses cbfstool when it installs the stage in the image. I would like to make the tools link those symbols at the right location but leave allocation of that space out of the ELF.

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.

2010-12-08second round name simplification. drop the <component>_ prefix.stepan
the prefix was introduced in the early v2 tree many years ago because our old build system "newconfig" could not handle two files with the same name in different paths like /path/to/usb.c and /another/path/to/usb.c correctly. Only one of the files would end up being compiled into the final image. Since Kconfig (actually since shortly before we switched to Kconfig) we don't suffer from that problem anymore. So we could drop the sb700_ prefix from all those filenames (or, the <componentname>_ prefix in general) - makes it easier to fork off a new chipset - makes it easier to diff against other chipsets - storing redundant information in filenames seems wrong Signed-off-by: <stepan@coresystems.de> Acked-by: Patrick Georgi <patrick@georgi-clan.de> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6150 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

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.

2010-10-12Reduce duplicate definition in CAR code.Warren Turkal
Macros for the register addresses for the MTRR MSRs are already defined in include/cpu/x86/car.h. This patch uses those macros instead of creating a second instance of that same data. I also added a few macros to the amd mtrr.h to make the MSR naming more consistent.

2010-10-01Factor out common CAR asm snippets.Uwe Hermann
This makes the CAR implementations a lot more readable, shorter and easier to follow, and also reduces the amount of uselessly duplicated code. For example there are more than 12 open-coded "enable cache" instances spread all over the place (and 12 "disable cache" ones), multiple "enable mtrr", "save BIST", "restore BIST", etc. etc. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5902 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2010-10-01CAR simplifications, typos, readability improvements (trivial).Uwe Hermann
- Use some more #defines instead of hard-coding values. - Merge multiple movl/orl or movl/andl lines into one where possible. - Add some TODOs in places which seem to have either an incorrect code or incorrect comment. - Fix typos: s/for/from/, s/BSC/BSP/, s/size/carsize/.

2010-09-29Factor out fill_processor_name() and strcpy() functions.Uwe Hermann
The fill_processor_name() function was duplicated in multiple model_*_init.c files, move it into a new src/cpu/x86/name directory. The strcpy() function was also duplicated multiple times, move it to <string.h> where we already have similar functions.
