Thanks a lot. I tested patches [1-4] on nios2 boards with "ut time" and 
"sleep". It works fine.

I would suggest that we do not need the additional "counter-64bit" 
property by requiring the timer always return 64 bits count. We can 
provide an inline func to do the 32/64 conversion for all 32 bits timers.

Best regards,
Thomas
