* Purpose: This file contains the functions used for power on and off
*          management of the board.
*          In case of RVM_PWR_SWE, this file contains also the
*          functions used for charger plug and unplug management.
*          They are all called after the occurence of the ABB interrupt.
*
* Author:  Candice Bazanegue (c-brille@ti.com)
*
* The present FreeCalypso version is heavily modified from TI's original,
* for the new FreeCalypso way of managing handset on/off state.
