[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.

76 * Timer handling for EP93xx
77 *************************************************************************
78 * The ep93xx has four internal timers. Timers 1, 2 (both 16 bit) and
79 * 3 (32 bit) count down at 508 kHz, are self-reloading, and can generate
80 * an interrupt on underflow. Timer 4 (40 bit) counts down at 983.04 kHz,
81 * is free-running, and can't generate interrupts.
82 *
83 * The 508 kHz timers are ideal for use for the timer interrupt, as the
84 * most common values of HZ divide 508 kHz nicely. We pick one of the 16
85 * bit timers (timer 1) since we don't need more than 16 bits of reload
86 * value as long as HZ >= 8.
87 *
88 * The higher clock rate of timer 4 makes it a better choice than the
89 * other timers for use in gettimeoffset(), while the fact that it can't
90 * generate interrupts means we don't have to worry about not being able
91 * to use this timer for something else. We also use timer 4 for keeping
92 * track of lost jiffies.
