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.

2022-03-29soc/mediatek: Ensure PERST# deassertion time follows the specJianjun Wang
According to the PCIe CEM specification, the deassertion of PERST# should occur at least 100ms after the assertion. To ensure the 100ms delay requirement is met, calculate the elapsed time since assertion. If it is smaller than 100ms, do an extra delay. TEST=Build pass and boot up to kernel successfully via SSD on Dojo board, here is the measured PERST# time: [DEBUG] mtk_pcie_domain_enable: 432517 us elapsed since assert PERST# [INFO ] mtk_pcie_domain_enable: PCIe link up success (17 tries) And the SSD information in boot log is as follows: == NVME IDENTIFY CONTROLLER DATA == PCI VID : 0x15b7 PCI SSVID : 0x15b7 SN : 21517J440114 MN : WDC PC SN530 SDBPTPZ-256G-1006 RAB : 0x4 AERL : 0x7 SQES : 0x66 CQES : 0x44 NN : 0x1 Identified NVMe model WDC PC SN530 SDBPTPZ-256G-1006 BUG=b:178565024 BRANCH=cherry Signed-off-by: Jianjun Wang <jianjun.wang@mediatek.com> Change-Id: Ie2b7b6174abdf951af5796ab5ed141c45f32fc71 Reviewed-on: https://review.coreboot.org/c/coreboot/+/62933 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Yu-Ping Wu <yupingso@google.com>
