After 5 months ;-), I do have a question.

In r3998 a pointer to NUTRTC has been added as a parameter to all RTC driver functions. From what I can see, we have a single registered RTC only, stored in

 static NUTRTC *reg_rtc;

IMHO the extra parameter generates much more code than accessing a global variable.

Beside that, it broke existing code, e.g. app/ftpd/. Although that had been marked deprecated, we should not do this without a good reason.

So, here's my question: What was the reason for this change?

Regards,

Harald
