Hi:
Does some one have any comments about this driver?
Thanks

> v3 --> v4:
> [0] use the nand_ids{} as the nand database, drop my own database.
> [1] remove the patch for DMA enginer, Shawn will submit his own version.
> [2] use the platform_id to distinguish different Archs.
> [3] fix the strange coding style.
> [4] others.

> v2 --> v3:
> [0] merge the imx23 and imx28 into one file(including the header file).
> [1] remove the unuse registers in the headers.
> [2] fix DMA bugs
> [3] add bus width field to nand_attr{}
> [4] others
>
> v1 --> v2:
> [0] merge the common files into the gpmi-nfc-main.c
> [1] change the code to get the clock.
> [2] remove the timing in the nand_device_info{}
> [3] fix DMA errors
> [4] add the nand_device_info.[ch] to generic code
> [5] use the chip->onfi_version for the ONFI nand
> [6] useless init
> [7] others
