From 81671750134cc98c33ac4441d7a6eacf59448641 Mon Sep 17 00:00:00 2001
From: nbd <nbd@3c298f89-4303-0410-b956-a3cf2f4a3e73>
Date: Fri, 3 Nov 2006 22:03:50 +0000
Subject: rename the <boardname>-<kernelversion> directories of base-files to
 just <boardname>, so that the broadcom stuff can share files across kernel
 versions. adding back <boardname>-<kernelversion> for version specific
 overrides is still possible
