The board revision is detected accessing to the pmic, that is not available before relocation (I2C). This generates the following error:
CPU: Freescale i.MX35 rev 2.0 at 532 MHz. Reset cause: WDOG <reg num> = 7 is invalid. Should be less than 0 Board: MX35 PDK 1.0
The revision number is wrong, as a default value is printed (tested on a mx35pdk Rev. 2.0).
Move the output in the board_late_init(), when pmic can be accessed.
