    powerpc/book3e: Add Chroma as a new WSP/PowerEN platform. · cc35b676
    Jimi Xenidis authored
    This patch add the Chroma platform to WSP/PowerEN, which is a PCIe
    card (a defconfig is included).
    
    The card includes an H8 service processor that is used to manage the
    card.  The H8 is connected over the second serial UART on the PowerEN
    chip so this patch includes a simple 16550 driver to enable
    communication, mostly for "power off" and "rebooting".
    
    This patch also includes a, WSP specific, "halt" method that will shut
    of all A2 cores but still leave power on at the chip level.  This is
    desirable, especially if you wish to interrogate the chip with a
    hardware probe after the halt.
