Patch from Lennert Buytenhek This patch adds support for the Cirrus ep93xx series of CPUs. The ep93xx is an ARM920T based CPU with two VICs, PL010 based UARTs, IrDA, MaverickCrunch floating point coprocessor, between 24 and 64 GPIOs, ethernet, OHCI USB and, depending on the model, pcmcia, raster engine, graphics accelerator, IDE controller and a bunch of other stuff. This patch adds the core ep93xx support code, and support for the Glomation GESBC-9312-sx and the Technologic Systems TS-72xx SBCs.
