From 89a7a87f084c657f8e32b513a77b50eca07e17ec Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Sat, 6 Dec 2008 13:11:14 +0100 Subject: at91: Choose environment variables location within make config target This patch adds the possiblity to choose the media where the environment will be located. This allow to choose this fundamental configuration without editing config files. Documentation file added.
