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.

2022-02-11src/mainboard/emulation/qemu-power9: require hb-mode=onYaroslav Kurlaev
"hb-mode" is a -machine flag for QEMU. "hb" stands for Hostboot, which is OpenPower firmware created by IBM. QEMU for PPC64 can run initial program in two different modes: * hb-mode=off with load address 0x00000000 * hb-mode=on with load address 0x08000000 Real hardware always loads firmware at 0x08000000 and coreboot shouldn't require a special build to be run on QEMU. Memory layout is updated to reflect change of load address.

2021-07-09ppc64/byteorder.h: define use of big endianKrystian Hebel
All of the build configuration is set to produce big endian image on PPC64. In addition, the toolchain produced by coreboot-sdk does not include little endian libraries so it is not possible to build LE image even when that configuration is changed. This patch changes byte order definition which is required for proper work of functions that deal with endianness, like read_{le,be}*() or {le,be}*toh(). It also revealed bugs related to the endianness on BE targets that are addressed in the following patches.

These platforms return to romstage from FSP only after already having torn CAR down. A copy of the entire CAR region is available and discoverable via HOB. Previously, CBMEM console detected on-the-fly that CAR migration had happened and relocated cbmem_console_p accoringlin with car_sync_var(). However, if the CAR_GLOBAL pointing to another object inside CAR is a relative offset instead, we have a more generic solution that can be used with timestamps code as well.

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.
