From 86a20fb920bd198105acf7b1191117f566d637ed Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 16 Feb 2008 07:40:36 -0500 Subject: [PATCH 1/6] Blackfin: move bootldr command to common code This moves the Blackfin-common bootldr command out of the BF537-STAMP specific board directory and into the common directory so that all Blackfin boards may utilize it.
