UBIFS corruptions on NOR-Flash

[Roshni Shah]

Its not mainline. I am using this driver from Freescale, which has
support for Quad/DDR read and support for IMX6 SoloX.

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/mtd/spi-nor/fsl-quadspi.c?h=imx_3.14.28_1.0.0_ga

Mainline driver excludes the above support.

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/mtd/spi-nor/fsl-quadspi.c

Also, even though the Freescale driver supports Quad / DDR read, I am
not using that for this test. My device tree just uses regular read.

Thanks,
Roshni
