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.

2023-09-18libpayload: Add vboot and reboot utility functionsJakub Czapiga
Patch adds: - vboot_fail_and_reboot() for vboot failures handling. - reboot() weak implementation for payloads to implement, used by vboot_fail_and_reboot(). - vboot_recovery_mode_enabled() to check if recovery mode flag is set in vboot context. Implemented for future libcbfs implementation of VBOOT_CBFS_INTEGRATION in libpayload.

2021-09-20device/mmio: Make buffer_to_fifo32() take a const bufferJulius Werner
The input buffer to the buffer_to_fifo family of functions is only read, so it can be a const pointer. (Also, remove the MIPS check in libpayload for these functions... the MIPS architecture has been removed a while ago.)

2019-08-22Add buffer_to/from_fifo32(_prefix) helpersJulius Werner
Many peripheral drivers across different SoCs regularly face the same task of piping a transfer buffer into (or reading it out of) a 32-bit FIFO register. Sometimes it's just one register, sometimes a whole array of registers. Sometimes you actually transfer 4 bytes per register read/write, sometimes only 2 (or even 1). Sometimes writes need to be prefixed with one or two command bytes which makes the actual payload buffer "misaligned" in relation to the FIFO and requires a bunch of tricky bit packing logic to get right. Most of the times transfer lengths are not guaranteed to be divisible by 4, which also requires a bunch of logic to treat the potential unaligned end of the transfer correctly. We have a dozen different implementations of this same pattern across coreboot. This patch introduces a new family of helper functions that aims to solve all these use cases once and for all (*fingers crossed*).
