When using softRTC, the system will still synchronize with the hardRTC, on
boot (to initialize) and on a couple other conditions such as timezone
change, day change etc.

Nop - It doesn't work! I can however build the platform but the watch in
the taskbar isn't still runnning which mean that the clock still gets the
value from the RTC hardware (because there is no battery attached so it
doesn't change).
It is not because you see the clock in the taskbar that the RTC hardware
is sollicited (i.e. is the soft RTC does its job, the hard RTC will no be
used anymore.)
If you want to make sure of something, build a debug version and put a
breakpoint in the Bare_GetRealTime function of
Platform\Common\Src\X86\Common\Rtc\CMOS.C.
Any other suggestions on how to stop the RTC (I don't need it at all -
and I don't think the system need it as well - am I right?)?
No. You are not right. The system makes a very intensive usage of the
"System Time", which is normally delivered by the RTC. Actually, each time
a thread or a file or anything that has a timestamp in it is created, the
GetSystemTime function is called and ends in Bare_GetRealTime (if you
don't have an efficient soft RTC active!)
