How can the PSWITCH feature be disabled in software?

[rfa]

We tried making changes to  ..boot_prep/init-mx28.c to disable PSWITCH, but were unable to.  Any suggestions on what exact changes are required to do this?

[art]

The power-off functionality of the PSWITCH signal can be disabled by setting the FASTFALLPSWITCH_OFF bit in the HW_POWER_RESET register.

The power-on functionality of the PSWITCH signal can be disabled by setting the DISABLE_PSWITCH bit in the HW_RTC_PERSISTENT0 register.

The entering recovery mode functionality of the PSWITCH signal cannot be disabled in any way.

Have a great day,
Artur
