About RTC of PXA270
Please tell me about RTC of PXA270.
In my board, RTC Counter Register (RCNR) is cleared when I reset a CPU. (RCNR become zero).
So, "date" is always UNIX epoch when Linux is started.
RCNR is changed when I carry out "hwclock -w".
However, the other RTC registers do not change.
My question is as follows.
1. When a CPU was reset, is it right movement that RCNR is cleared?
2. if yes, where is "date" stored?
