This patchset reworks the drivers ECC calculation to align more with the Linux driver gpmi-nand.c. It aims to implements minimal ECC support as supported by the NAND chip.
This is the rebased version after moving MXS NAND to Kconfig.
In this fourth revision the SPL driver is also taken care off. I went with a conservative approach by initializing the SPL driver as before since I do not have a device where I could test more involved changes.
