Much of the timer code is re-implemented for each platform/arch yet it is all pretty much the same code.
This series introduces a common implementation of timer functions and simplifies the platform code down to 2 or 3 config defines or 2 simple functions. It is intended for platforms with 32-bit freerunning timers. I've converted SH and a couple of ARM platforms as an example, but there are many more still that can be converted. This probably could be extended to work with 16-bit timers as well.
I've compiled on ARM, SH4, and PPC.
v2: - Make timer code common for all architectures - Convert SH timer to common code - Drop mx27 due to include mess. - Add converting versatile to common code
