[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.

/*

|
|
|
* The EP93xx has two external crystal oscillators. To generate the
|
|
|
|
* required high-frequency clocks, the processor uses two phase-locked-
|
|
|
|
* loops (PLLs) to multiply the incoming external clock signal to much
|
|
|
|
* higher frequencies that are then divided down by programmable dividers
|
|
|
|
* to produce the needed clocks. The PLLs operate independently of one
|
|
|
|
* another.
