From 3c63eff2d97007c1ed9bea63388e97931dc67970 Mon Sep 17 00:00:00 2001 From: Timo Ketola Date: Tue, 17 Jan 2012 10:42:19 +0200 Subject: [PATCH] i.MX25: Set OOB size (MXC NFC) SPAS register (OOB size) is left wrong after reset with respect to 2KiB page NAND chip. That will lead to ECC errors after 'reset halt'.
