From: Kumar Gala Date: Thu, 23 Aug 2007 03:53:39 +0000 (-0500) Subject: [MTD] Remove dead maps X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=34a27ffdf59f80fe165f5c56a0be57d55b6da63d;p=linux-beck.git [MTD] Remove dead maps The tqm834x map Kconfig options depends on TQM834x which does not exist anywhere else in the kernel. The pq2fads map Kconfig/makefile support was removed a while ago but the actual file persisted.
