Andrew Victor c53c9cf60e [ARM] 4331/3: Support for Micrel/Kendin KS8695 processor
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.
