Lennert Buytenhek e7736d47a1 [ARM] 3369/1: ep93xx: add core cirrus ep93xx support
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.
