[edk2] [PATCH V2] MdeModulePkg EhciPei: Support IoMmu

2017-11-16 Thread Star Zeng
V2: Halt HC at EndOfPei. Update the EhciPei driver to consume IOMMU_PPI to allocate DMA buffer. If no IOMMU_PPI exists, this driver still calls PEI service to allocate DMA buffer, with assumption that DRAM==DMA. Cc: Jiewen Yao Contributed-under: TianoCore Contribution
