The current sbsa-ref cannot use EHCI controller which is only able to do 32-bit DMA, since sbsa-ref doesn't have RAM below 4GB. Hence, this uses XHCI to provide a usb controller with 64-bit DMA capablity instead of EHCI. Signed-off-by: Yuquan Wang<wangyuquan1236@phytium.com.cn>
Can you share firmware side so it can be tested? The more I deal with EDK2 the more I understand why people go U-Boot.
