2022-11-09Revert "mb/aopen/dxplplusu: Remove board"Kyösti Mälkki
This reverts commit eb76a455cd39ec59b7f2ba28baeec9538befd59e and applies minor fixes to make it build again. PARALLEL_MP was working prior to board removal and no relevant SMI handlers were implemented. So NO_SMM choice is now selected.

2022-08-26x86: Zero SMBIOS region before writing tablesJonathon Hall
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. Normal cold boot: [ 0.008615] ACPI: RSDP 0x00000000000F6190 000024 (v02 COREv4) [ 0.008619] ACPI: XSDT 0x0000000099B480E0 00005C (v01 COREv4 COREBOOT 00000000 CORE 20220331) [ 0.008624] ACPI: FACP 0x0000000099B4A2A0 000114 (v06 COREv4 COREBOOT 00000000 CORE 20220331) [ 0.008634] ACPI: DSDT 0x0000000099B48280 00201F (v02 COREv4 COREBOOT 20110725 INTL 20220331) ...

2022-07-14commonlib: Substitude macro "__unused" in compiler.hBill XIE
Since there are many identifiers whose name contain "__unused" in headers of musl libc, introducing a macro which expands "__unused" to the source of a util may have disastrous effect during its compiling under a musl-based platform. However, it is hard to detect musl at build time as musl is notorious for having explicitly been refusing to add a macro like "__MUSL__" to announce its own presence. Using __always_unused and __maybe_unused for everything may be a good idea. This is how it works in the Linux kernel, so that would at least make us match some other standard rather than doing our own thing (especially since the other compiler.h shorthand macros are also inspired by Linux).

2022-06-07commonlib: Clean up compiler.hJulius Werner
This patch contains several minor cleanups related to compiler.h: - Replace __always_unused() (which is a Linux-specific concept that doesn't make sense without also having __maybe_unused(), and had zero uses in the codebase) with __unused() which moves here from helpers.h - Add __underscores__ to the names of all attributes in the compiler attribute shorthand macros. This is necessary to make them work in files where the same name was already used for an identifier (e.g. cbfstool/cbfs.h's `unused` array of file types). - Remove libpayload's own copy of compiler.h and make it directly pull in the commonlib/bsd copy.

2022-03-08timestamps: Rename timestamps to make names more consistentJakub Czapiga
This patch aims to make timestamps more consistent in naming, to follow one pattern. Until now there were many naming patterns: - TS_START_*/TS_END_* - TS_BEFORE_*/TS_AFTER_* - TS_*_START/TS_*_END This change also aims to indicate, that these timestamps can be used to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

2022-02-25arch/x86: consolidate HPET base address definitionsFelix Held
Both the HPET_BASE_ADDRESS define from arch/x86/include/arch/hpet.h and the HPET_ADDRESS Kconfig option define the base address of the HPET MMIO region which is 0xfed00000 on all chipsets and SoCs in the coreboot tree. Since these two different constants are used in different places that however might end up used in the same coreboot build, drop the Kconfig option and use the definition from arch/x86 instead.

According to util/kbc1126/README.md, for these ECs to work, the address and size of their two firmware should be written to $s-0x100` (`$s` means the image size, done with kbc1126_ec_insert), which means that every existing section (especially those used to store code) should not overlap this address, otherwise the bootblock will get damaged when inserting firmwares of the EC. In this commit, ecfw_ptr is a structure initialized at build time according to CONFIG_KBC1126_FW1_OFFSET and CONFIG_KBC1126_FW2_OFFSET (to do so, they should be redefined as hex), and linked to CONFIG_ECFW_PTR_ADDR within bootblock, so kbc1126_ec_insert is not needed at build time any more.
