2024-05-26libpayload: Add x86_64 (64-bit) supportSubrata Banik
This patch introduces x86_64 (64-bit) support to the payload, building upon the existing x86 (32-bit) architecture.

2024-03-17libpayload: Make GPL commonlib includes available to payloads and testsJulius Werner
CB:77968 made some non-BSD commonlib files part of libpayload when CONFIG_LP_GPL is set. This patch exports those headers to the payload (again only when CONFIG_LP_GPL is set) so that payloads can also call the functions in them directly. Also make those includes available to tests so that their functions can be tested. There's no menuconfig for unit tests, so they are included unconditionally, but this should be fine since the tests are standalone and won't have to link with any proprietary third-party code.

2023-03-07libpayload: bin/lpgcc allow to call without filesThomas Heijligen
When building libflashrom ontop of libpayload, meson calls the lpgcc wrapper with -xc but without a file to obtain information about the C compiler. To make this work guard $_LIBGCC with -xnone in the lpgcc wrapper. -xnone tells the compiler to interpret the following files of libpayload by their suffix, not the privious given -x option.

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.

2022-01-15libpayload: Install vboot headers and add include paths to lpgccJakub Czapiga
New CBFS API uses commonlib/bsd/cbfs_serialized.h, which includes vboot's vb2_sha.h. And, because vboot's includes are not available in libpayload's installation directory nor in lpgcc paths, it was causing compilation errors. This patch fixes this issue. lpgcc will look for `vboot` directory like it is doing for `include` directory to create correct paths. However, if payload will be built using libpayload's build dir as a base, then vboot headers from 3rdparty/vboot will be used, as there is no way to pass VBOOT_SOURCE from makefile to lpgcc. Moreover, this patch moves VBOOT_SOURCE to the main Makefile to make it available for installation target, to install headers from vboot directory provided by caller.

2021-10-11libpayload: Add mock architectureJakub Czapiga
Mock architecture can be used to build libpayload using host compiler. It can be enabled by setting ARCH_MOCK=y in the dotconfig. It sets LITTLE_ENDIAN=y, as most machines these days use little-endian CPUs. Libpayload will use HOSTCC as CC, HOSTLD as LD, etc. instead of tools provided by xcompile. Mock architecture configuration can be used by payloads for testing purposes. Thanks to it, tests can be architecture-independent, and can be executed without requiring compatible Kconfig options, e.g. ARCH_ARM64=y for ARM64 machine. However, one has to provide implementation for most architecture-specific functions present in arch/* directories.

2020-11-08libpayload: Add compiler.h to compiler parametersJacob Garber
Headers in libpayload define various structs like so: struct struct_name { ... } __packed; However, these header files do not include the compiler.h macro that defines what __packed is, so they are actually defining a variable named __packed and *not* declaring a packed struct. This leads to defining the same variable multiple times, which was caught by GCC 10. Add compiler.h to the compiler parameters so it is included in all files automatically.

A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

We don't always want to use ARMv7 code when building for ARM, so we should separate out the ARMv7 code so it can be excluded, and also make it possible to include code for some other version of the architecture instead, all per build component for cases where we need more than one architecture version at a time. The tegra124 bootblock will ultimately need to be ARMv4, but until we have some ARMv4 code to switch over to we can leave it set to ARMv7.

2014-08-05libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.Gabe Black
When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.

2013-02-15libpayload: fix compiler flagsRonald G. Minnich
lpgcc was unconditionally setting -m32. Most of the flags it sets in the common case are right, however: no need to duplicate them everywhere, and we only want to change the common ones in one place, so it would be a shame to duplicate _CFLAGS all over the place. So add another variable, _ARCHEXTRA, which can be used to add special flags to _CFLAGS. We onlu use it at present for the x86; this may change. This allows us to get through compiling on arm and x86.
