[v2] Add PEI BlockIo support for NVM Express devices

[edk2] [PATCH v2 1/4] MdeModulePkg: Add definitions for EDKII PEI NVME host controller PPI

Posted by Hao Wu 7 years, 7 months ago

Introduces the below PPI:

struct EDKII_NVM_EXPRESS_HOST_CONTROLLER_PPI {
  EDKII_NVM_EXPRESS_HC_GET_MMIO_BAR       GetNvmeHcMmioBar;
  EDKII_NVM_EXPRESS_HC_GET_DEVICE_PATH    GetNvmeHcDevicePath;
};

The GetNvmeHcMmioBar service will provide the caller with the MMIO BAR
address of each NVMe HC within the system;

The GetNvmeHcDevicePath service will provide the caller with the device
path information of each NVMe HC.
