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.
