From 21c8db9eff95260e543535dfc6f27164c4c0c0ff Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Wed, 14 Jun 2006 21:39:48 +0100 Subject: [PATCH] [MTD] Restore MTD_ROM and MTD_RAM types Let's not attempt the abolition of mtd->type until/unless it's properly thought through. And certainly, let's not do it by halves.
