So coming back to the specific problem here.
I think we need 'nandecc' back in u-boot till atleast all systems have
migrated to BCH16 or whatever highest ecc-scheme which can be
supported on OMAP devices.
Forgot to mention, one more way of updating boot-loaders with
different ecc-scheme via

Hi Enric,
Thanks a lot for fixing this.
When adding NAND support for the IGEP boards I used as a base the
example from Documentation/devicetree/bindings/mtd/gpmc-nand.txt and I
wrongly assumed that bch8 was also the ECC scheme used in the legacy
IGEP board file. Sorry for the inconvenience.
