From ba8dcca78dc071fb1f419a920c82c18b10f9eff3 Mon Sep 17 00:00:00 2001 From: Felix Radensky Date: Mon, 6 Jun 2011 05:06:07 +0000 Subject: [PATCH] mx31ads: Fix environment location on flash At the moment u-boot and u-boot environment on flash have overlapping addresses, so each u-boot update erases the environment. Fix this by placing evironment right after u-boot. Also, remove confusing comment about environment location.
