From 656441478ed55d960df5f3ccdf5a0f8c61dfd0b3 Mon Sep 17 00:00:00 2001 From: Mark Marshall Date: Thu, 26 Jan 2017 16:18:27 +0100 Subject: mtd: nand: ifc: Fix location of eccstat registers for IFC V1.0 The commit 7a654172161c ("mtd/ifc: Add support for IFC controller version 2.0") added support for version 2.0 of the IFC controller. The version 2.0 controller has the ECC status registers at a different location to the previous versions. Correct the fsl_ifc_nand structure so that the ECC status can be read from the correct location for both version 1.0 and 2.0 of the controller.
