I tested this patch with the imx6q-ard board and imx6dl-ard board.
For the gpmi nand test result:
[1] imx6q-ard: We can pass the bonie++ stress test with the imx6q-ard board.
[2] imx6dl-ard: But we fails to read the nand ID with the imx6dl-ard board.
In other word, this gpmi can _not_ works with this patch.
But without this patch, the imx6dl-ard works fine.
In section 4.1, the spec tells us that the 0x1b0b0 is just the "default
settings for the each pad",
not the right settings for the each pad.
thanks
