The patch is based on branch "imx-for-3.1" of tree :
      git://git.pengutronix.de/git/imx/linux-2.6.git

The general-purpose media interface(GPMI) controller is a flexible interface
to up to several NAND flashs.

The Bose Ray-Choudhury Hocquenghem(BCH) module is a hardware ECC accelerator.

With the help of BCH, the GPMI controller can choose to do the hardware ECC or
not.

v6 --> v7:
	[0] rename RES_SIZE to GPMI_NAND_RES_SIZE.
	[1] move gpmi-nand.h to `include/linux/mtd/` directory.
	[2] remove comment for new pad control.
	[3] others

v5 --> v6:
	[0] rename `gpmi-nfc` to `gpmi-nand`.
	[1] remove ->exit() in structure gpmi_nand_platform_data{}.
	[2] drop the macros for the resource's definition of gpmi-nand.
	[3] add a new pad control `MXS_PAD_CTRL_12MA`. 
	[4] others.

v4 --> v5:
	[0] split out the mach code and the machine code.

v3 --> v4:
	merge the GPMI-NFC device code to the new branch.
