Add core support for the Kendin/Micrel KS8695 processor family. It is an ARM922-T based SoC with integrated USART, 4-port Ethernet Switch, WAN Ethernet port, and optional PCI Host bridge, etc. http://www.micrel.com/page.do?page=product-info/sys_on_chip.jsp This patch is based on earlier patches from Lennert Buytenhek, Ben Dooks and Greg Ungerer posted to the arm-linux-kernel mailing list in March 2006; and Micrel's 2.6.9 port.
