From: Brit Chesley <brit.ches...@amd.com> This patchset introduces the SPI driver stack as defined in the Platform Initialization specification Volume 5 chapter 18 (DXE) and Volume 4 chapter 12 (SMM). The SPI stack decouples the SPI chip details from the SPI controller and SPI bus configuration details to enable silicon vendors to write drivers effectively. This patchset also introduces the SpiHcPlatformLib, which allows for OEMs to handle low level SPI host controller details while using the generic SPI bus/hc drivers.
