* ARMV7: Fix build for non-OMAP3 boardsSteve Sakoman2010-11-041-1/+1
| | | | | | | | | | | | | | | Commit c3d3a54 uses CONFIG_ARMV7 to determine whether to call the v7_flush_cache_all function. This breaks the build for all non-OMAP3 boards (like Panda and OMAP4430SDP) since there is only a v7_flush_cache_all implementation for OMAP3. This patch uses CONFIG_OMAP3XXX instead of CONFIG_ARMV7 so that only boards with a v7_flush_cache_all will make the call. Tested on Beagle, Overo, Panda, and OMAP4430SDP Signed-off-by: Steve Sakoman <steve.sakoman@linaro.org> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-131-0/+36
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
