This sets CONFIG_SYS_HZ to 1000 as required, and completely rewrites timer code, which is now both correct and much smaller. Unused functions like udelay_masked() have been removed as no driver uses them, even the ones that are not currently active for this board. mtu.h is copied literally from the kernel sources.

I've used mtu.h from kernel sources and done the other changes as requested (the extra variable just to return it was a mishap from an earlier printf I needed to find a misconfig).
for the record what is its precision now?
it counts at 2.4MHz, so the 1000HZ tick has no approximation and udelay is correct with sub-microsecond error. I'll use in soft_i2c, needed to turn on the LCD light.
cpu/arm926ejs/nomadik/mtu.h | 45 +++++++++++
if it's ok with I'll move it to include/asm-arm/arch-nomadik/
