Hi Artem, Brian,

> - PATCH-3: re-ordered call to is_elm_present() for later updates ELM driver

> - [Patch 1/3] removed MTD_NAND_OMAP_BCH8 &

> 	ECC scheme selectable via nand DT (nand-ecc-opt).

> - PATCH-4 <DROPPED> update DT attribute for ti,nand-ecc-opt
> 	- received feedback to keep DT mapping independent of linuxism
