2023-04-29ACPI: Make FADT entries for RTC/CMOS architecturalKyösti Mälkki
For AMD, replace name RTC_ALT_CENTURY with RTC_CLK_ALTCENTURY that points to same offset. Since the century field inside RTC falls within the NVRAM space, and could interfere with OPTION_TABLE, it is now guarded with config USE_PC_CMOS_ALTCENTURY. There were no reference for the use of offset 0x48 for century.

2023-04-27arch/x86: Disable walkcbfs_asm code when CONFIG_CBFS_VERIFICATION is setJulius Werner
walkcbfs_asm is a simple CBFS implementation in assembly to find a file on a system with memory-mapped SPI flash. It seems to be mostly unused nowadays and is only still called for early microcode loading on some old systems (e.g. FSP 1.1 and older). Using this implementation with CONFIG_CBFS_VERIFICATION is unsafe because it does not verify the hashes the way the normal CBFS code does. Therefore, to avoid potential security vulnerabilities from creeping in, this patch makes sure the code cannot be compiled in when CBFS_VERIFICATION is active. That means it won't be supported on the old boards using this for microcode loading. Ideally CONFIG_CBFS_VERIFICATION should have a `depends on` to make this dependency more obvious in menuconfig, but the configs actually using this code are not easy to untangle (e.g. CONFIG_MICROCODE_UPDATE_PRE_RAM is just set everywhere by default although only very few boards are really using it, and a lot of different old Intel CPU models are linking in src/cpu/intel/car/non-evict/cache_as_ram.S without being united under a single Kconfig so that's not easy to change). To keep things simple, this patch will just prevent the code from being built and result in a linker error if a bad combination of Kconfigs is used together. Later patches can clean up the Kconfigs to better wrap that dependency if the affected boards are still of enough interest to be worth that effort.

2023-04-26soc/intel: Introduce ioapic_get_sci_pin()Kyösti Mälkki
According to ACPI Release 6.5 systems supporting PIC (i8259) interrupt mechanism need to report IRQ vector for the SCI_INT field. In PIC mode only IRQ0..15 are allowed hardware vectors. This change should cover section 5.2.9 to not pass SCI_INT larger than IRQ15. Section 5.2.15.5 needs follow-up work. Care should be taken that ioapic_get_sci_pin() is called after platform code has potentially changed the routing from the default. It appears touched all platforms except siemens/mc_aplX currently program SCI as IRQ9.

2023-03-13cpu/x86/cache: CLFLUSH programs to memory before runningArthur Heymans
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).

2022-12-17lib: Hook up libhwbase in romstageJeremy Compostella
It's hidden behind the configuration option `CONFIG_ROMSTAGE_LIBHWBASE'. This also adds some glue code to use the coreboot console for debug output and our monotonic timer framework as timer backend. Running Ada code in romstage and more particular libhwbase brings a few challenges as global initialized variables are not supported in Cache-As-Ram mode. 1. The libhwbase dynamic mmio driver implementation makes the Gnat compiler generate some global initialized variables. For this reason, when compiled for romstage or for romstage and ramstage the static mmio driver is enforced (`HWBASE_STATIC_MMIO'). 2. The Gnat compiler generates elaboration functions to initialize program data at runtime. These elaboration functions are called by the romstage_adainit() function. The data references symbols suffixed by `_E'. Even though these symbols, at compilation time, do not contain any data and are filled with zeros, the Gnat compiler installs them in the .data section. Since these symbols are actually filled with zeros, it is safe to install them in the .bss section. cf. https://docs.adacore.com/gnat_ugn-docs/html/gnat_ugn/gnat_ugn/elaboration_order_handling_in_gnat.html#elaboration-code This patch requires the libhwbase https://review.coreboot.org/c/libhwbase/+/69854 CL.

2022-11-29Revert "src/arch/x86: Use core apic id to get cpu_index()"Arthur Heymans
This reverts commit 095c931cf12924da9011b47aa64f4a6f11d89f13. Previously cpu_info() was implemented with a struct on top of an aligned stack. As FSP changed the stack value cpu_info() could not be used in FSP context (which PPI is). Now cpu_info() uses GDT segments, which FSP does not touch so it can be used. This also exports cpu_infos from cpu.c as it's a convenient way to get the struct device * for a certain index. TESTED on aldrvp: FSP-S works and is able to run code on APs.

Clear the SMBIOS region before writing SMBIOS tables. On librem_mini and librem_mini_v2, CBMEM allocations are offset by 4K for reboots relative to the cold boot. This means the unused SMBIOS region could contain the first 4K of the ACPI tables from the last boot (including the signature), which prevents Linux from booting. The CBMEM 4K offset appears to be due to FSP allocating memory differently between cold boot and reboot, this appears to be normal and causes the CBMEM base address to change. It is not clear why Linux examines an ACPI signature found in this region, but boot logs over serial confirm that it sees the corrupt table. The table is supposed to be found just below 1M, and kernel source appears to look in this region, but it is definitely finding the corrupt table in CBMEM.

With CBFS verification, cbfstool (CB:41121) needs bootblock to be present in coreboot.pre in order to locate the metadata hash stored in it. Therefore we have to ensure that bootblock is added to CBFS before other CBFS files are added. To solve the problem, create the 'add_bootblock' function, and call it in the coreboot.pre recipe. Because bootblock.bin is now a prerequisite of coreboot.pre, it will get built even if CONFIG_BOOTBLOCK_IN_CBFS=n.
