RFC, i.MX28 related

[Juergen Beisert]

Hi list,

the i.MX28 SoC has a nice "feature" which prevents the "intended" usage of its 
watchdog.

When the SoC is powered via its 5 V power supply input the watchdog triggers a 
simple system reset when it barks. But when the SoC is powered via the 
battery supply input only, the watchdog powers off the whole chip instead, 
because it resets the PMIC.

But we are in luck: a register bit exists to select a system reset or power 
off for the battery powered case when the watchdog barks. It only defaults to 
the power off setting after reset.

Should we re-program this bit to the system reset setting for all i.MX28 based 
system (e.g. in the i.MX28 generic part of Barebox) or better on a board by 
board base?
