From 015038fa72a63a8424743deb2d9e7f85cdc3c70a Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Wed, 4 Mar 2015 17:12:19 +1030 Subject: external/opal-prd: Correct partition offset The start of the partition was not used when sending the size to the mtd_{read,write} calls. This meant they were unconditionally reading and writing to the start of the flash, instead of the partition.
