Subject: omap3: Rework board.c for !CONFIG_SYS_L2CACHE_OFF
X-Git-Tag: v2013.01-rc2~146^2~3^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=57f588be60eac8135cdfb366237fbf6e6dc2d316;p=kernel%2Fu-boot.git

omap3: Rework board.c for !CONFIG_SYS_L2CACHE_OFF

When CONFIG_SYS_L2CACHE_OFF is defined we end up with a few warnings
currently.  Re-order functions so that we don't have that anymore.
