Modified Files: src/sys/arch/arm/nvidia [nick-nhusb]: tegra_xusb.c src/sys/dev/pci [nick-nhusb]: xhci_pci.c src/sys/dev/usb [nick-nhusb]: usb.h xhci.c xhcireg.h xhcivar.h Log Message: Parse the extended capabilies to and log each controller port to SS/HS bus root hub ports. Create/attach the two buses and adapt the xhci_roothub_ctrl to deal with both buses and sets of roothub ports.
