True. You mean gsm_exit() and bootstrap_exit() I think.
These were added to free resources in a shutdown. If freeing is pointless,
in a reboot case, and stale resources don't matter, well, we can kill these
2 functions.

I'll try to test the patch serie this evening after my daywork,
and give feedback.

The main facts of mioa701 board regarding halting/rebooting:
 - watchdog reset kills RTC time
 - there is no GPIO reset (which would preserve time, sic ...)
 - mioa701 is based on PXA272 (arm v5)

Cheers.
