From: Greg Ungerer <[email protected]> The timer code used on the ColdFire 53xx series is abusing the old 16bit timer code. The hardware module it uses is really the more modern DMA timer hardware module. It bends the reads/writes and modifies some addresses so that it basically works.
It would be much better to use the modern Programmable Interrupt Timer hardware module that these SoC contain. This PIT timer is used on all the other modern ColdFire family members. We also have DMA timer code that we will in the future use as a more accurate clock source and cycle counter. So the idea here is to clean up this usage to free up the timer hardware. I don't have any 53xx based hardware, so I have not been able to run time test this. If anyone can test this and confirm that it works as expected that would be great.
