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... Also, I don't know if multiprocessor boards (abit bp6?) would need to be handled differently. Abuild-tested.

CONFIG_HAVE_ACPI_RESUME == 1 getting rid of ugly define in romstage.c 2) the patch implements get_cbmem_toc in chipset specific way if defined. On Intel targets it should be unchanged. On K8T890 the the cbmem_toc is read from NVRAM. Why you ask? Because we cannot do it as on intel, because the framebuffer might be there making it hard to look for it in memory (and remember we need it so early that everying is uncached) 3) The patch removes hardcoded limits for suspend/resume save area (it was 1MB) on intel. Now it computes right numbers itself. 4) it impelements saving the memory during CAR to reserved range in sane way. First the sysinfo area (CAR data) is copied, then the rest after car is disabled (cached copy is used). I changed bit also the the copy of CAR area is now done uncached for target which I feel is more right. I think I did not change the Intel suspend/resume behaviour but best would be if someone can test it. Please note this patch was unfinished on my drive since ages and it would be very nice to get it in to prevent bit rotten it again. Now I feel it is done good way and should not break anything. I did a test with abuild and it seems fine.

initializing VGA happens pretty much as the last thing before starting the payload. Hence, drop VGA console support, as we did in coreboot v3. - Drop VGA and BTEXT console support. Console is meant to be debugging only, and by the time graphics comes up 99% of the risky stuff has already happened. Note: This patch does not remove hardware init but only the actual output functionality. The ragexl driver needs some extra love, but that's for another day - factor out die() and post() - drop some leftover RAMBASE < 0x100000 checks.

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.

2010-10-19When debug logging is enabled, a message such as '* AP 02 timed out:02010501'Scott Duplichan
is sometimes logged. The reason is that the AP first sets a completion value such as 0x13, which is what function wait_cpu_state() is waiting for. Then a short time later, the AP calls function init_fidvid_ap(). This function sets a completion value of 01. When logging is off, wait_cpu_state is fast enough to see the initial completion value for each of the APs. But with logging enabled, one or more APs may go on to complete function init_fidvid_ap, which sets the completion value to 01. While mostly harmless, the timeout does increase boot time. This patch eliminates the timeout by making function wait_cpu_state recognize 01 as an additional valid AP completion value.

2010-10-06Convert all Intel 440BX boards to Cache-as-RAM (CAR).Uwe Hermann
- Add "select CACHE_AS_RAM" in src/cpu/intel/slot_1/Kconfig. - Add the following in src/cpu/intel/slot_1/Makefile.inc: cpu_incs += $(src)/cpu/intel/car/cache_as_ram.inc - Remove "select ROMCC" from all 440BX board Kconfig files. - Drop all early_mtrr_init() calls, that's done by CAR code now. Various small fixes were needed to make it build: - Drop do_smbus_recv_byte(), do_smbus_send_byte(), do_smbus_write_byte(), those were never called anyways. - Remove the "static" from the main() functions in romstage.c files. - Always call dump_spd_registers() from the 440BX debug.c, but use "#if CONFIG_DEBUG_RAM_SETUP" to only have that code if RAM debugging is enabled in menuconfig. - Drop all "lib/ramtest.c" #includes and ram_check() calls (even if commented out) from romstage.c's, as we've done for most other boards. - Add missing #includes or prototypes. Some of the prototypes will be removed later when we get rid of the #include'd .c files. Abuild-tested for all boards, and boot-tested on A-Trend ATC-6220.

2010-10-04Add missing Intel Pentium II/III era CPU IDs.Uwe Hermann
Add links to the respective Intel specification updates or manuals where the IDs are listed. Mention the possible core steppings of each CPU ID. There are duplicate IDs in model_6xx and model_68x for now, not sure if those should be eliminated, but there were already duplicates before this patch, so that's probably an extra issue to look into. Abuild-tested. 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@5909 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

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
