2012-01-09ACPI: mark empty get_cst_entries() weakSven Schnelle
This function prevents the linker from choosing the right get_cst_entries(), preventing writing the _CST tables.

2011-12-05Bootblock does not need a unique boot_cpu()Kyösti Mälkki
Detection of a CPU being a BSP CPU is not dependent of the existence of northbridge and/or southbridge init code in the bootblock. Even if CONFIG_LOGICAL_CPUS==0, boot_cpu() can get executed on an AP CPU of a hyper-threading CPU and needs to return actual BSP bit from MSR.

2011-10-13mptable: Refactor lintsrc generationPatrick Georgi
We copied pretty much the same code for generating mptable entries for local interrupts (with some notable exceptions). This change moves these lines into a generic function "mptable_lintsrc" and makes use of it in many places. The remaining uses of smp_write_lintsrc should be reviewed and replaced by mptable_lintsrc calls where possible, and smp_write_lintsrc made static. This patch was generated using Coccinelle: @@ expression mc; expression isa_bus; @@ -smp_write_lintsrc(mc, mp_ExtINT, MP_IRQ_TRIGGER_DEFAULT|MP_IRQ_POLARITY_DEFAULT, isa_bus, 0x0, MP_APIC_ALL, 0x0); -smp_write_lintsrc(mc, mp_NMI, MP_IRQ_TRIGGER_DEFAULT|MP_IRQ_POLARITY_DEFAULT, isa_bus, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, isa_bus); @@ expression mc; expression isa_bus; @@ -smp_write_lintsrc(mc, mp_ExtINT, MP_IRQ_TRIGGER_EDGE|MP_IRQ_POLARITY_HIGH, isa_bus, 0x0, MP_APIC_ALL, 0x0); -smp_write_lintsrc(mc, mp_NMI, MP_IRQ_TRIGGER_EDGE|MP_IRQ_POLARITY_HIGH, isa_bus, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, isa_bus); @m@ identifier mc; expression BUS; @@ -#define IO_LOCAL_INT(type, intr, apicid, pin) smp_write_lintsrc(mc, (type), MP_IRQ_TRIGGER_EDGE | MP_IRQ_POLARITY_HIGH, BUS, (intr), (apicid), (pin)); ... -IO_LOCAL_INT(mp_ExtINT, 0x0, MP_APIC_ALL, 0x0); -IO_LOCAL_INT(mp_NMI, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, BUS); Change-Id: I97421f820cd039f5fd753cb0da5c1cca68819bb4 Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/244 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones <marcj303@gmail.com>

2011-03-08Move cmos.default handling to bootblockPatrick Georgi
The cmos.default code wasn't actually used so far, due to an oversight when forward-porting this feature from an old branch. - Extend walkcbfs' use by factoring out the stage handling into C code. - New sanitize_cmos() function that looks if CMOS data is invalid and cmos.default exists and if so overwrites CMOS with cmos.default data. - Use sanitize_cmos() in both bootblock implementations. - Drop the need to reboot after writing CMOS: CMOS wasn't used so far, so we can go on without a reboot. - Remove the restriction that cmos.default only works on CAR boards. - Always build in cmos.default support on boards that USE_OPTION_TABLE.

2010-12-16Get mptable OEM/product ID from kconfig variables.Uwe Hermann
We currently use "COREBOOT" unconditionally as the "OEM ID" in our mptable.c files, and hardcode the mainboard name in mptable.c like this: mptable_init(mc, "DK8-HTX ", LAPIC_ADDR); However, the spec says "OEM ID: A string that identifies the manufacturer of the system hardware." (Table 4-2, page 42) so "COREBOOT" doesn't match the spec, we should use the hardware vendor name. Thus, use CONFIG_MAINBOARD_VENDOR which we have already as the "OEM ID" (truncate/fill it to 8 characters as per spec). Also, use CONFIG_MAINBOARD_PART_NUMBER (the board name) as "product ID", and truncate/fill it to 12 characters as per spec, if needed. Abuild-tested.
