Caleb Connolly	2bd5bcaf7d	iommu: qcom-smmu: add qcom generic compatible ... With the exception of SDM845, most other Qualcomm SoCs have the Qualcomm specific (but not SoC) specific SMMU compatible string. Add it here so we can match those without having to add individual SoCs to the list here. Signed-off-by: Caleb Connolly <caleb.connolly@linaro.org>	2024-04-23 13:29:28 +02:00
Caleb Connolly	42839c0fdf	iommu: qcom-smmu: fix debugging ... The priv struct was wrong in dump_boot_mappings(). Causing errors when compiling with -DDEBUG. Fix this.

Caleb Connolly	d3db45cb9c	iommu: add qcom-hyp-smmu ... Add a basic implementation of the ARM SMMU. This driver is intended for use on Qualcomm platforms where the SMMU has been configured by a previous bootloader, cannot be turned off, and doesn't support BYPASS streams. It keeps all existing stream mappings and only creates new ones for stream ids that aren't already configured. This driver is necessary to support peripherals that perform DMA which weren't configured by the previous stage bootloader (for example USB). It works by allocating a context bank using identity mapping (as U-Boot doesn't use virtual addresses). Signed-off-by: Caleb Connolly <caleb.connolly@linaro.org>	2023-12-21 11:59:49 -05:00
