2024-06-20cbfstool: Read XIP stage alignment requirements from ELFArthur Heymans
On x86_64 romstage can contain page tables and a page table pointer which have an larger alignment requirement of 4096. Instead of hardcoding it, read if from the ELF phdrs.

2024-05-29tree: Use Wcalloc-transposed-args command optionElyes Haouas
GCC-14 documentation says "The first argument to calloc is documented to be number of elements in array, while the second argument is size of each element, so calloc(n, sizeof (int)) is preferred over calloc(sizeof(int), n)."

2024-03-19Makefile.mk: Include build/dsdt.d at the same time as DEPENDENCIESNicholas Chin
Instead of including the generated dependency file during the evaluation of asl_template, add it to the DEPENDENCIES variable so that it is included at the same time as the rest of the .d files in the top level Makefile. This makes the handling of .d files cleaner as all of them are processed in the same way. Tracking all of them in a single variable also prevents any from being missed if any post-processing is performed on them, such as running them through the fixdep utility from the Linux kernel project to replace the config.h dependency with only the configs that are used. This should be safe since asl_template is evaluated while calling includemakefiles, which is occurs before the files in DEPENDENCIES are included. TEST: 1. Build dell/e6400 2. Run `touch src/mainboard/dell/e6400/dsdt.asl` (defined as a prerequisite of build/dsdt.aml in build/dsdt.d) 3. Run `make --debug=b` 4. Verify that dsdt.aml was rebuilt due dsdt.asl being newer than target Change-Id: Ie8271d1e172395917f2859c8bbfd2041ddc572ca Signed-off-by: Nicholas Chin <nic.c3.14@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/80383 Reviewed-by: Nico Huber <nico.h@gmx.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Martin L Roth <gaumless@gmail.com>
2024-03-15treewide: Move stdlib.h to commonlibMaximilian Brune
This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since all code is BSD licensed anyway. It also moves some code from libpayloads stdlib.h to commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is useful for a subsequent commit that adds devicetree.c into commonlib. Also we don't support DMA on arm platforms in coreboot (only libpayload) therefore `dma_malloc()` has been removed and `dma_coherent()` has been moved to architecture specific functions. Any architecture that tries to use `dma_coherent()` now will get a compile time error. In order to not break current platforms like mb/google/herobrine which make use of the commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a stub has been added to arch/arm64/dma.c.

2024-01-26util: Rename Makefiles from .inc to .mkMartin Roth
The .inc suffix is confusing to various tools as it's not specific to Makefiles. This means that editors don't recognize the files, and don't open them with highlighting and any other specific editor functionality. This issue is also seen in the release notes generation script where Makefiles get renamed before running cloc.
