    PPC32: Add support for the PPC 440 family of embedded processors. · 272069b7

    This has three main parts: (1) support for the 440GP and 440GX processors,
    (2) support for the "Ebony" and "Ocotea" reference boards for those processors,
    and (3) support for 64-bit physical addresses.  The 440GP and 440GX are "Book E"
    processors, and this introduces a CONFIG_BOOKE and some definitions that apply
    to all Book E processors.
    
    Having 64-bit physical addresses means that PTEs are now 64 bits.  The PTE pages
    stay at 4kB, and the pgdir expands to 8kB.
