From 57f588be60eac8135cdfb366237fbf6e6dc2d316 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Tue, 30 Oct 2012 22:23:28 -0700 Subject: 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.
