Instead of having a magic entry in the CPU device ID table list to tell find_cpu_driver that it has reached the end of the list, introduce and use CPU_TABLE_END.

2023-02-08arch/x86/cpu: introduce and use device_match_maskFelix Held
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.

2022-08-25soc/amd: rework SPI flash MMIO region handlingFelix Held
Only 16 MByte of the SPI flash can be mapped right below the 4 GB boundary. In case of a larger SPI flash size, still only the 16 MByte region starting at 0xff000000 can be configured as WRPROT and be reserved for the MMIO mapped SPI flash region. The next 16 MByte MMIO region starting at address 0xfe000000 contain for example the LAPIC MMIO region, the ACPIMMIO region and the UART/I2C controller MMIO regions which shouldn't be configured as WRPROT. Reserving this region for the MMIO mapped SPI flash would also result in an overlap with the MMIO resources mentioned above. In the case of a smaller SPI flash, reserving the full 16 MByte flash MMIO region makes sure that the resource allocator won't try to put anything else in the lower parts of the 16 MByte SPI mapping region. To avoid the issues described above, always reserve/cache the maximum amount of 16 MBytes of flash that can be mapped below 4 GB. TEST=On boards with 16 MByte SPI flash chips, the resulting image of a timeless build doesn't change with this patch. Verified this on Chausie (Mendocino), Majolica (Cezanne), Cereme (Picasso) and Google/Careena (Stoneyridge). On Mandolin (Picasso) with an 8 MByte flash, the resulting image of a timeless build is different, but neither the coreboot console output nor the Linux dmesg output shows any errors that might be related to this change.

2021-11-03soc/amd/*/cpu: handle mp_init_with_smm failureFelix Held
When the mp_init_with_smm call returns a failure, coreboot can't just continue with the initialization and boot process due to the system being in a bad state. Ignoring the failure here would just cause the boot process failing elsewhere where it may not be obvious that the failed multi-processor initialization step was the root cause of that. I'm not 100% sure if calling do_cold_reset or calling die_with_post_code is the better option here. Calling do_cold_reset likely here would likely result in a boot-failure loop, so I call die_with_post_code here.

2021-10-22cpu/x86/mp_init: move printing of failure message into mp_init_with_smmFelix Held
Each CPU/SoC checks the return value of the mp_init_with_smm and prints the same error message if it wasn't successful, so move this check and printk to mp_init_with_smm. For this the original mp_init_with_smm function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm function is created which then calls do_mp_init_with_smm, prints the error if it didn't return CB_SUCCESS and passes the return value of do_mp_init_with_smm to its caller. Since no CPU/SoC code handles a mp_init_with_smm failure apart from printing a message, also add a comment at the mp_init_with_smm call sites that the code might want to handle a failure.

The procedure dev_find_slot has 3 main uses. To find configuration (devicetree), to verify if a particular device is enabled at build \ time, and to get the address for PCI access while in bootblock/romstage. The third use can be hidden by using macros defined in pci_devs.h, making it very clear what PCI device is being accessed. replace the temporary pointers to device used with PCI access with SOC_XXX_DEV where XXX is the device being accessed, and remove the setting of the temporary pointers.

Extend the existing reset handling features in Stoney Ridge to plan for, and recognize, warm resets. The ColdRstDet bit is always zero on a cold reset, and is intended as a mechanism for the BIOS to determine the type of a reset that occurred. Set ColdRstDet=1 after all cores have been initialized, so that any subsequent reset may be identified as warm/cold. A later patch will check the value during mp_init.

Relocate setting the temp range MTRR, for the SPI flash device, to after completion of mp_init. The mp_init functionality mirrors the BSP's exact MTRR settings into the AP cores. The ranges need to be the correct calculated values and not some temporary setting. This solves an MTRR sync issue on APUs with more than two cores, i.e. more than a single compute-unit. MTRRs within a CU are shared so the AP always stays in sync.

2017-09-27amd/stoneyridge: Convert MP init to mp_init_with_smmMarshall Dawson
Change the Stoney Ridge SOC to a more modern method for setting up the multiple cores. Add a new cpu.c file for most of the processor initiliazation. Build mp_ops with the necessary callbacks. Note also that this patch removes cpu_bus_scan. Rather than manually find CPUs and add them to the devicetree, allow this to be done automatically in the generic mp_init.c file. SMM information is left blank in mp_ops to avoid having mp_init.c install a handler at this time. A later patch will add TSEG SMM capabilities for the APU. This patch also contains a hack to mask the behavior of AGESA which configures the MTRRs and Tom2ForceMemTypeWB coming out of AmdInitPost. The hack immediately changes all WB variable MTRRs, on the BSP, to UC so that all writes to memory space will make it to the DRAM.
