mtd: nand: fsl_ifc: Read ECCSTAT0 and ECCSTAT1 registers for IFC 2.0
Due to missing information in Hardware manual, current implementation doesn't read ECCSTAT0 and ECCSTAT1 registers for IFC 2.0. Add support to read ECCSTAT0 and ECCSTAT1 registers during ecccheck for IFC 2.0. Fixes: 656441478ed5 ("mtd: nand: ifc: Fix location of eccstat registers for IFC V1.0") Cc: stable@vger.kernel.org # v3.18+ Signed-off-by: Jagdish Gediya <jagdish.gediya@nxp.com> Reviewed-by: Prabhakar Kushwaha <prabhakar.kushwaha@nxp.com> Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
