From: Stefan Agner stefan@agner.ch

commit ea56fb282368ea08c2a313af6b55cb597aec4db1 upstream.

With commit 3cf32d180227 ("mtd: nand: vf610: switch to mtd_ooblayout_ops") the driver started to use the NAND cores default large page ooblayout. However, shortly after commit 6a623e076944 ("mtd: nand: add ooblayout for old hamming layout") changed the default layout to the old hamming layout, which is not what vf610_nfc is using. Specify the default large page layout explicitly.
