[v2] Platform/SbsaQemu: use XHCI to replace EHCI

[edk2-devel] [PATCH edk2-platforms v2 0/3] Platform/SbsaQemu: use XHCI to replace EHCI

Posted by Yuquan Wang 9 months, 3 weeks ago

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
