Re: [edk2-devel][PATCH v1 0/2] Add EDKII_PCI_DEVICE_PPI support to EDK2

["Maciej Czajkowski" <maciej.czajkowski@intel.com>]

For now, the priority will be to add the support for AHCI and NVMe. However, in the future the plan is to have support in all of these drivers.

Regards,
Maciej

Sorry for a question, if the EDKII_PCI_DEVICE_PPI were added to edk2, would there be a plan to add support to:
* NVMe
* UFS
* SD/MMC
* USB (XHCI, EHCI and UHCI)

Best Regards,
Hao Wu
