I dont think this works for OMAP4 (which also uses A9, PL310) - we use an smc #0 with service 0x109 (I have to reconfirm) to set l2 aux_ctrl.

we might want to ensure that: a) The "setting" part of things get into a weak function with default function that may be SoC dependent if needed b) there be revision checks as needed to add this. c) each configuration be adequately isolated perhaps?
Adding a common support for this seems to be far more complex then I expected.
Maybe someone could come up with a proper common solution for this. If not, then we should go with the mx6 specific patch for the time being.
Maybe the following can help? (reposting) http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/214436
