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.

Build fix for src/arch/i386/boot/acpi.c if !CONFIG_SMP Also check for acpi_slp_type 2 in acpi_is_wakeup, since S2 uses the same acpi wakeup vector as S3. Add _PTS/_WAK methods to turn off/on the CPU/case fans and blink the power LED while sleeping. acpi_get_sleep_type() is in a seperate file i82371eb_wakeup.c because it is used in both romstage and ramstage after patch 3/3, whereas i82371eb_early_pm.c is used only in romstage. I used the name acpi_get_sleep_type instead of acpi_is_wakeup_early because I think acpi_is_wakeup_early is a bit misleading as a name since it doesn't return a boolean value. Other chipsets so far only ever set acpi_slp_type to 0 and 3, so the added check for acpi_slp_type == 2 (resume from S2) should not change behaviour of other boards: northbridge/intel/i945/northbridge.c:256:extern u8 acpi_slp_type; northbridge/intel/i945/northbridge.c:263: acpi_slp_type=0; northbridge/intel/i945/northbridge.c:267: acpi_slp_type=3; northbridge/intel/i945/northbridge.c:271: acpi_slp_type=0; southbridge/intel/i82801gx/i82801gx_lpc.c:171:extern u8 acpi_slp_type; southbridge/via/vt8237r/vt8237r_lpc.c:149:extern u8 acpi_slp_type; southbridge/via/vt8237r/vt8237r_lpc.c:238: acpi_slp_type = ((tmp & (7 << 10)) >> 10) == 1 ? 3 : 0 ; southbridge/via/vt8237r/vt8237r_lpc.c:239: printk(BIOS_DEBUG, "SLP_TYP type was %x %x\n", tmp, acpi_slp_type); Change-Id: I13feff0b8f49aa988e5467cdbef02981f0a6be8a Signed-off-by: Tobias Diedrich <ranma+coreboot@tdiedrich.de> Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/188 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

The previous code does a full flush of the uart after every character. Unfortunately, this can cause transmission delays on some serial ports. This patch changes the code so that it does a flush at the end of every printk instead of at the end of every character. This reduces the time it takes to transmit serial messages (up to 9% on my Asrock e350m1 board). It also makes the transmission time more consistent which is important when performing timing tests via serial transmissions.

2011-06-22Add the coreboot config to CBFSCristian Măgherușan-Stanciu
The CBFS will contain a new file, named 'config' of type 'raw' that is a stripped-down version of the .config file that was used to build the current coreboot image. For space savings, all the comments and empty lines were removed from the original config, except for one that lists the coreboot git revision that's built into the image. This is done in order to easily reproduce the work of someone else when only having their ROM image. In theory the reproduce could even be automated by a new dedicated make target. This should work even with abuild now.

2011-04-20Simplify coreboot's console/console.hStefan Reinauer
- shift most (romcc) code out of console.h into arch/x86/lib/romcc_console.c - rename arch/x86/lib/printk_init.c to .../romstage_console.c - drop FUNCTIONS_FOR_PRINT since __console_tx_* are already functions, so there should not be any side effects to eliminating another indirection.

2011-04-19Recently the 3 projects using the new AMD reference code have beenScott Duplichan
failing the check for globals (or statics) in romstage. This causes ASRock E350M1, AMD Inagua, and AMD Persimmon builds to fail with the message "Do not use global variables in romstage". The message is working as intended. It is detecting data declared as 'static' when 'static const' was intended. The code executes correctly because it never tries to modify the data. To make reference code updates easy, it is probably best to avoid modifying the AMD provided code if possible. The following change bypasses the "Do not use global variables in romstage" check for the AMD reference code only.
