-* Set DCDC2 to 1.2v for all boards irrespective of board version, or power source.
+* Set DCDC2 to 1.2v for all power sources and board revs except for A1
 * Set USB current trip point to 1300mA for all boards and power sources.
 * Only Skip setting of MPU frequency to 720MHz for A1 and USB-powered boards.
 
-Credits to Jason for noticing this. Tested with 20 reboots over USB.
+Credits to Jason for noticing this. Tested with several reboots over USB on a Rev A2/3.
+
+v2 changes:
+Take care of not upping DCDC2 and LDO voltages for A1.
+For A1- only operation done is to set the USB current limit.
