    powerpc/xics: Rewrite XICS driver · 0b05ac6e
    Benjamin Herrenschmidt authored
    This is a significant rework of the XICS driver, too significant to
    conveniently break it up into a series of smaller patches to be honest.
    
    The driver is moved to a more generic location to allow new platforms
    to use it, and is broken up into separate ICP and ICS "backends". For
    now we have the native and "hypervisor" ICP backends and one common
    RTAS ICS backend.
    
    The driver supports one ICP backend instanciation, and many ICS ones,
    in order to accomodate future platforms with multiple possibly different
    interrupt "sources" mechanisms.
