The purpose of those changes is to introduce the way to enumerate and assign resources in PEI for the systems with more than one PCI root. Here is a need to have an interface that will support such a mechanizm. For now, the part that performs the enumeration will be implemented in the silicon code. Sample code can be seen here: https://github.com/mczaj/edk2-platforms/commit/d443062e58f9fba228869b54f2546d9735b3b506 Cc: Hao A Wu <hao.a...@intel.com> Cc: Ray Ni <ray...@intel.com> Cc: Liming Gao <gaolim...@byosoft.com.cn> Maciej Czajkowski (2): MdeModulePkg: Add EDKII_PCI_DEVICE_PPI definition MdeModulePkg/AhciPei: Use PCI_DEVICE_PPI to manage AHCI device MdeModulePkg/Bus/Ata/AhciPei/AhciPei.c | 615 +++++++++++++++----- MdeModulePkg/Bus/Ata/AhciPei/DevicePath.c | 44 -- MdeModulePkg/Bus/Ata/AhciPei/AhciPei.inf | 5 +- MdeModulePkg/Include/Ppi/PciDevice.h | 32 + MdeModulePkg/MdeModulePkg.dec | 3 + 5 files changed, 493 insertions(+), 206 deletions(-) create mode 100644 MdeModulePkg/Include/Ppi/PciDevice.h -- 2.27.0.windows.1 --------------------------------------------------------------------- Intel Technology Poland sp. z o.o. ul.
