From ed764db2887aa90efb8c5a5d79775d5d18c26b27 Mon Sep 17 00:00:00 2001 From: Dmitry Eremin-Solenikov Date: Thu, 23 Jun 2011 12:33:52 +0400 Subject: mtd: maps: drop edb7312 support EDB7312 isn't supported by mainline kernel, this driver wasn't working before recent fixes, the same functionality can be achieved via physmap, so drop it now. If the board support will ever be submitted to mainline, one either can revert this commit, or use physmap mtd map driver.
