This patchset implements XHCI on sbsa-ref board to replace EHCI.
As sbsa-ref does not have DRAM below 4G, it cannot utilize EHCI
that only has 32-bit DMA capablity. Now this board has XHCI as
an available usb controller with 64-bit DMA capablity.
History:
v1 -> v2:
- rebased on master as v1 did not applied
- moved pcd setting in dec file into the first commit
Yuquan Wang (3):
Platform/Qemu/SbsaQemu/SbsaQemu.dsc: define XHCI Pcd settings
SbsaQemu: Drivers: Add initial support for XHCI
SbsaQemu: AcpiTables: Add XHCI info into DSDT
Adding Ard, Leif and Graeme to Cc.
