* cpu/amd/pi/00730f01/Kconfig: use hexadecimal CPU number in ACPIFelix Held2023-05-161-1/+1
| | | | | | | | | | | | | | | To match the rest of coreboot, also change this ACPI_CPU_STRING Kconfig setting to use hexadecimal CPU numbers for the ACPI CPU objects. Since this SoC has a maximum of 4 cores, this change will make no difference in the runtime behavior.

* acpi/Kconfig: move \_SB scope out of ACPI_CPU_STRINGFelix Held2023-05-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | In ACPI 1.0 the processor objects were inside the \_PR scope, but since ACPI 2.0 the \_SB scope can be used for that. Outside of coreboot some firmwares still used the \_PR scope for a while for legacy ACPI 1.0 OS compatibility, but apart from that the \_PR scope is deprecated. coreboot already uses the \_SB scope for the processor devices everywhere, so move the \_SB scope out of the ACPI_CPU_STRING to the format string inside the 3 snprintf statements that use the ACPI_CPU_STRING.

| | | | | | | | | | | | | | | | | | | | | | | | When cbmem is initialized in romstage and postcar placed in the stage cache + cbmem where it is run, the assumption is made that these are all in UC memory such that calling INVD in postcar is OK. For performance reasons (e.g. postcar decompression) it is desirable to cache cbmem and the stage cache during romstage. Another reason is that AGESA sets up MTRR during romstage to cache all dram, which is currently worked around by using additional MTRR's to make that UC. TESTED on asus/p5ql-em, up/squared on both regular and S3 resume bootpath. Sometimes there are minimal performance improvements when cbmem is cached (few ms).

Another reason is that getting certain data that requires searching from flash VPD or CMOS is not very ideal to be done in SMM, so in this change the value can be passed via the member variable in struct smm_runtime and be referenced directly in SMM. One example is that mainboard can get the desired SMM log level from VPD/CMOS, and pass SMM console log level via the variable and in SMM it can be referenced in get_console_loglevel() override function directly.

* arch/x86/cpu: introduce and use device_match_maskFelix Held2023-02-0817-108/+119
| | | | | | | | | | | | | | | | | | | | | Instead of always doing exact matches between the CPUID read in identify_cpu and the device entries of the CPU device ID table, offer the possibility to use a bit mask in the CPUID matching. This allows covering all steppings of a CPU family/model with one entry and avoids that case of a missing new stepping causing the CPUs not being properly initialized. Some of the CPU device ID tables can now be deduplicated using the CPUID_ALL_STEPPINGS_MASK define, but that's outside of the scope of this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | To deprecate VBOOT_VBNV_CMOS [1], replace VBOOT_VBNV_CMOS with VBOOT_VBNV_FLASH for samsung boards lumpy and stumpy. 0x8000 unused flash space is allocated for RW_NVRAM. Previously BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES was selected for CPU_INTEL_HASWELL, CPU_INTEL_MODEL_{2065X,206AX} and others (see [2]). However, there seems to be no particular reason on those platforms. We've dropped the config for haswell. Now drop it for CPU_INTEL_MODEL_{2065X,206AX}, so that VBOOT_VBNV_FLASH can be enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | There are four requirements for the SMI to hit a printk() this commit now removes. Build must have DEBUG_SMI=y, otherwise any printk() is a no-op inside SMM. ASL must have a TRAP() with argument 0x99 or 0x32 for SMIF value. Platform needs to have IO Trap #3 enabled at IO 0x800. The SMI monitor must call io_trap_handler for IO Trap #3. At the moment, only getac/p470 would meet the above criteria with TRAP(0x32) in its DSDT _INI method. The ASL ignores any return value of TRAP() calls made. A mainboard IO trap handler should have precedence over a southbridge IO trap handler. At the moment we seem to have no cases of the latter to support, so remove the latter.
