Hi,

On latest Linux Kernel versions the selection of ecc option is done via devicetree property ti,nand-ecc-opt.
www.kernel.org/.../gpmc-nand.txt

On this version I am not sure how it can be changed.
You can follow the platform data pdata->ecc_opt variable to see where it gets set.

Regards,
Vishal

Platform data most probably is passed via gpmc_nand_init() API, follow where this API is called with what parameters.
