From 21c601bb2ec79be5c52a99bc6f4b513aff4fa236 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Thu, 4 Dec 2008 18:00:30 +0900 Subject: [PATCH] sh: remove ioport cruft and smc91x from se7343 Remove out-of-date se7343 ioport code including some old support for unknown-ne2000-pcmcia-card, cf-over-pcmcia and a mysterical smc91x that once must have been on a special daughterboard.
