2019-01-13arch/x86: Drop Kconfig AP_SIPI_VECTORKyösti Mälkki
This was used to check romcc-built bootblock and romstage agree about the location of 16-bit entrypoint. There was no need to customize it as bootblock size requirement did not grow. Just check for a fixed location at 4 GiB - 4 KiB. With C_ENVIRONMENT_BOOTBLOCK we can have a proper symbol for the purpose, since it appears in the same compilation unit. It will adjust if C_ENV_BOOTBLOCK_SIZE changes.

This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be set with values that are not power of 2. The region programmed as WB cacheable will include all of ROM_SIZE. Side-effects to consider: Memory region below flash may be tagged WRPROT cacheable. As an example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB. Since this can overlap CAR, we add an explicit test and fail on compile should this happen. To work around this problem, one needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and define a smaller region for WB cache. With this change flash regions outside CBFS are also tagged WRPROT cacheable. This covers IFD and ME and sections ChromeOS may use.

Here is a solution using the SSDT. Unfortunately iasl does not resolve simple arithmetic at compile time, so we can not use Add(DEFAULT_PMBASE, PCNTRL) in the Processor statement. This patch instead dynamically generates the processor statement. I can't use the speedstep generate_cpu_entries() directly since the cpu doesn't support speedstep. For now the code is in the southbridge directory, but maybe it should go into cpu/intel/ somewhere. IIRC notebook cpus of the era can already have speedstep, so it would probably be possible to pair the i82371eb with a speedstep-capable cpu...

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/.

2010-09-30Various cosmetic and coding style fixes in CAR code (trivial).Uwe Hermann
Also, whitespace fixes, consistency fixes, and drop some of the less useful comments. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5888 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2010-09-30Use existing, readable MTRR #defines instead of hardcoding numbers.Uwe Hermann
Replace $0x200 with $MTRRphysBase_MSR(0) etc. Also, move some #ifdef stuff a little bit around (should not affect any functionality) to make the Intel/AMD/VIA CAR implementations more similar and easier to compare.

2010-08-14My forgotten CAR cleanup patch...Stefan Reinauer
- Drop lots of dead code from the various cache_as_ram.inc files. - Use some descriptive macros instead of magic numbers for MTRR MSRs - drop unused duplicate descriptors from romstage GDT - slightly reformatting code and comments Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5696 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2010-04-27Since some people disapprove of white space cleanups mixed in regular commitsStefan Reinauer
while others dislike them being extra commits, let's clean them up once and for all for the existing code. If it's ugly, let it only be ugly once :-) Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5507 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

2010-04-14move cpu/x86/car to cpu/intel/car as previously discussed on the mailing list.Stefan Reinauer
this patch also slightly changes it so we have a single cache_as_ram.inc which requires no "help" from cache_as_ram_post.c and cache_as_ram_disable.c (or worse, a lot of cruft hacked right into romstage.c like on tyan s2735) Now all CAR code except the AMD Opteron/Athlon64 CAR code follows the new simpler scheme. I'll gladly leave src/cpu/amd/car to someone else ;-) Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5423 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
