From 41c7540d0c4e362212845aa2258c15aaa878665f Mon Sep 17 00:00:00 2001 From: "Wu, Josh" Date: Thu, 2 Apr 2015 14:13:47 +0800 Subject: [PATCH] mtd: atmel_nand: don't map the ROM table if no pmecc table offset in DT if atmel,pmecc-lookup-table-offset is not found in DT node, we don't need to map the ROM table as we will build a runtime gf table anyway.
