board without RTC

[Joachim Denil]

Hello,

Can someone tell me what the following functions should do in case there is
no RTC on the hardware board. My processor is a 405gpr. Which of these i
must implement. (maybe some code snippets...). I think the most important
one is calibrate_decr for it is necesary to calibrate_delay function.

Thanks...
