[edk2-devel] [PATCH 0/3] use XHCI to replace EHCI

[wangyuquan1236]

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.
