Dear Fabio Estevam,
From: Fabio Estevam fabio.estevam@freescale.com
Registers HW_PINCTRL_DRIVE9, HW_PINCTRL_DRIVE10, HW_PINCTRL_DRIVE11, HW_PINCTRL_DRIVE12, HW_PINCTRL_DRIVE13 and HW_PINCTRL_DRIVE14 control the drive strength and the voltage selection for the DDR pins.
The reset values of the voltage selection pins are '1', which is marked as 'reserved' in the mx23 reference manual.
Clear these bits for proper operation of DDR.
Also change MUX_CONFIG_EMI, which results in better stability and match the bootlets code from Freescale.

Lost of duplicated code here.
Best regards, Marek Vasut
