    Subject[PATCH v6 4/4] usb: host: Add ability to build new Broadcom STB USB drivers
    Date
    Add the build system changes needed to get the Broadcom STB XHCI,
    EHCI and OHCI functionality working. The OHCI support does not
    require anything unique to Broadcom so the standard ohci-platform
    driver is being used. The link order for XHCI was changed in the
    Makefile because of the way STB XHCI, EHCI and OHCI controllers
    share a port which requires that the XHCI driver be initialized
    first. Also update MAINTAINERS.
