From 0a9e4e772123fe3e2bb499d7d2160c4cfd8a3a8d Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 24 Jul 2009 16:34:32 -0400 Subject: unify {CONFIG_,}ENV_IS_EMBEDDED Some boards have fallen out of sync by defining CONFIG_ENV_IS_EMBEDDED manually. While it is useful to have this available to the build system, let's do it automatically rather than forcing people to opt into it.
