mtd: nand: omap: Revert to using software ECC by default
For v3.12 and prior, 1-bit Hamming code ECC via software was the default choice. Commit c66d039197e4 in v3.13 changed the behaviour to use 1-bit Hamming code via Hardware using a different ECC layout i.e. (ROM code layout) than what is used by software ECC. This ECC layout change causes NAND filesystems created in v3.12 and prior to be unusable in v3.13 and later. So revert back to using software ECC by default if an ECC scheme is not explicitely specified. This defect can be observed on the following boards during legacy boot -omap3beagle -omap3touchbook -overo -am3517crane -devkit8000 -ldp -3430sdp Signed-off-by: Roger Quadros <rogerq@ti.com> Tested-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
