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).

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.

2020-06-13treewide: Add Kconfig variable MEMLAYOUT_LD_FILEFurquan Shaikh
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows SoC/mainboard to provide a linker file for the platform. x86 already provides a default memlayout.ld under src/arch/x86. With this new Kconfig variable, it is possible for the SoC/mainboard code for x86 to provide a custom linker file as well. Makefile.inc is updated for all architectures to use this new Kconfig variable instead of assuming memlayout.ld files under a certain path. All non-x86 boards used memlayout.ld under mainboard directory. However, a lot of these boards were simply including the memlayout from SoC. So, this change also updates these mainboards and SoCs to define the Kconfig as required. BUG=b:155322763 TEST=Verified that abuild with --timeless option results in the same coreboot.rom image for all boards.

2020-01-28commonlib: Add commonlib/bsdJulius Werner
This patch creates a new commonlib/bsd subdirectory with a similar purpose to the existing commonlib, with the difference that all files under this subdirectory shall be licensed under the BSD-3-Clause license (or compatible permissive license). The goal is to allow more code to be shared with libpayload in the future. Initially, I'm going to move a few files there that have already been BSD-licensed in the existing commonlib. I am also exracting most contents of the often-needed <commonlib/helpers.h> as long as they have either been written by me (and are hereby relicensed) or have an existing equivalent in BSD-licensed libpayload code. I am also relicensing <commonlib/compression.h> (written by me) and <commonlib/compiler.h> (same stuff exists in libpayload). Finally, I am extracting the cb_err error code definitions from <types.h> into a new BSD-licensed header so that future commonlib/bsd code can build upon a common set of error values. I am making the assumption here that the enum constants and the half-sentence fragments of documentation next to them by themselves do not meet the threshold of copyrightability.

2019-07-12arch, include, soc: Use common stdint.hJacob Garber
There are only minimal differences between the architecture specific stdint.h implementations, so let's tidy them up and merge them together into a single file. In particular, - Use 'unsigned long' for uintptr_t. This was already the case for x86 and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64 used 'unsigned long long'. This change allows using a single integer type for uintptr_t across all architectures, and brings it into consistency with the rest of the code base, which generally uses 'unsigned long' for memory addresses anyway. This change required fixing several assumptions about integer types in the arm code. - Use _Bool as the boolean type. This is a specialized boolean type that was introduced in C99, and is preferrable over hacking booleans using integers. romcc sadly does not support _Bool, so for that we stick with the old uint8_t. - Drop the least and fast integer types. They aren't used anywhere in the code base and are an unnecessary maintenance burden. Using the standard fixed width types is essentially always better anyway. - Drop the UINT64_C() macro. It also isn't used anywhere and doesn't provide anything that a (uint64_t) cast doesn't. - Implement the rest of the MIN and MAX numerical limits. - Use static assertions to check that the integer widths are correct.

2018-10-11selfboot: remove bounce buffersRonald G. Minnich
Bounce buffers used to be used in those cases where the payload might overlap coreboot. Bounce buffers are a problem for rampayloads as they need malloc. They are also an artifact of our x86 past before we had relocatable ramstage; only x86, out of the 5 architectures we support, needs them; currently they only seem to matter on the following chipsets: src/northbridge/amd/amdfam10/Kconfig src/northbridge/amd/lx/Kconfig src/northbridge/via/vx900/Kconfig src/soc/intel/fsp_baytrail/Kconfig src/soc/intel/fsp_broadwell_de/Kconfig The first three are obsolete or at least could be changed to avoid the need to have bounce buffers. The last two should change to no longer need them. In any event they can be fixed or pegged to a release which supports them. For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the value needed in 1999 for the 32-bit Linux kernel, the original ramstage) to 0xe00000 (14 Mib) which will put the non-relocatable x86 ramstage out of the way of any reasonable payload until we can get rid of it for good. 14 MiB was chosen after some discussion, but it does fit well: o Fits in the 16 MiB cacheable range coreboot sets up by default o Most small payloads are well under 14 MiB (even kernels!) o Most large payloads get loaded at 16 MiB (especially kernels!) With this change in place coreboot correctly still loads a bzImage payload. Werner reports that the 0xe00000 setting works on his broadwell systems.
