The Cycle CouNTer on ARM cannot be used reliably as it wraps around rather quickly and can be altered by user space (on Minix). Furthermore, it's buggy when wrapping and is not implemented at all on the Linaro Beagleboard emulator. This patch programs GPTIMER10 as a free running clock at 1.625 MHz (it doesn't generate interrupts). It's memory mapped into every process, which enables libsys to provide micro_delay().
