From b3e336c51d02c678a4d15573f4edb5834f39bb36 Mon Sep 17 00:00:00 2001 From: Maximilian Brune Date: Sat, 16 Sep 2023 19:49:39 +0200 Subject: treewide: Move stdlib.h to commonlib 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.
