2023-02-09arch/x86/include/cpu: introduce CPU_TABLE_END CPU table terminatorFelix Held
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. Since the vendor entry in the CPU device ID struct is compared against X86_VENDOR_INVALID which is 0, use X86_VENDOR_INVALID instead of the 0 in the CPU_TABLE_END definition. TEST=Timeless build for Mandolin results in identical image.

2023-02-08soc/amd/mendocino/cpu: use CPUID_ALL_STEPPINGS_MASKFelix Held
Use CPUID_ALL_STEPPINGS_MASK as CPUID match mask to support all Mendocino steppings that might be available in the future. Right now it shouldn't change any behavior.

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.

2022-08-11treewide: Rename Sabrina to MendocinoJon Murphy
'Mendocino' was an embargoed name and could previously not be used in references to Skyrim. coreboot has references to sabrina both in directory structure and in files. This will make life difficult for people looking for Mendocino support in the long term. The code name should be replaced with "mendocino".
