From 8f627247f651e80834d7b0441328151be180b335 Mon Sep 17 00:00:00 2001 From: Kevin Cernekee Date: Wed, 7 Jul 2010 17:30:10 -0700 Subject: mtd-utils: move libmtd source files to lib/ subdirectory Source files for libmtd, crc32, and fec are scattered throughout the tree. Move them to a central location so they can be built into a common "libmtd.a" library used by all mtd-utils programs. This patch only renames/deletes files and does not change the content. Also modify the build system and source code so that libmtd.a can be built from a "common" location (lib/). Statically link all utilities at the top level with libmtd.a . Minor changes to mkfs.ubifs to allow using the common crc32 implementation.
