From ede6b0d3600b11aaeacc0316bb18ab6e58aa9541 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 17 Apr 2011 18:32:28 +0000 Subject: [PATCH] rootfs_split: Allow using MTDPART_OFS_APPEND macro for offset of rootfs. Use offset from struct mtd_part instead of struct mtd_partition for defining the new partitions. This enables the usage of MTDPART_OFS_APPEND macro in struct mtd_partition.
