[U-Boot] [PATCH 13/34] Blackfin: bf561-ezkit/ibf-dsp561: invert env offset/addr logic

Mike Frysinger vapier at gentoo.org
Sun Apr 3 10:58:20 CEST 2011


Have CONFIG_ENV_ADDR be based on CONFIG_ENV_OFFSET rather than the other
way around so that we can use CONFIG_ENV_OFFSET during build.  It also
avoids a little address duplication.
