From 75cb594f03ce3d5d32197687abcd6de41acae023 Mon Sep 17 00:00:00 2001 From: blogic Date: Mon, 25 Aug 2014 16:30:44 +0000 Subject: [PATCH] kernel: add own Kconfig for OpenWrt mtdsplit drivers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There are pretty many OpenWrt patches against mtd subsystem resulting in a bit of mess and growing maintenance cost. My idea is to use an extra "mtdsplit" directory with OpenWrt specific files (including Kconfig). This is the first step to achieve this. This patch adds a "mtdsplit" directory with Kconfig and replaces 4 patches with a single one.
