From ff6d6965b4fb9b3d9387bde06956b7d2f9e9ba6b Mon Sep 17 00:00:00 2001 From: Joonyoung Shim Date: Wed, 6 Aug 2014 11:48:30 +0900 Subject: [PATCH] dfu:mmc: support to get partition information by name The partitions can have partition name like label. If partition name is exist, first get partition information by name than by partition number, so we can ignore hardcoding dependency of partition number.
