add the GPMI controller driver for IMX23/IMX28

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.

This driver is based the Shawn Guo's DMA patches for IMX23/IMX28,
please refer to :
	http://git.infradead.org/users/vkoul/slave-dma.git/commit...

add the mtd maillist.	

Huang Shijie (7):
  ARM: add GPMI support for imx23/imx28
  add the common code for GPMI driver
  add the database for the NANDs
  add GPMI support for imx23
  add GPMI support for imx28
  dmaengine: change the flags of request_irq()
  MTD : add GPMI driver in the config and Makefile
