We could do the same thing for > am43xx, but it seems better to allow turning it off and make the > code work in either case. > > This adds an inline wrapper for omap_l2_cache_init for the disabled > case, and removes the 'select' from OMAP4 so it becomes a user > visible option. > > Signed-off-by: Arnd Bergmann > Cc: linux-omap at vger.kernel.org Acked-by: Tony Lindgren
