set_pl310_ctrl_reg does use the Secure Monitor Call (SMC) to setup PL310 control register, however, that is something that is generic enough to be used for OMAP5 generation of processors as well. The only difference being the service being invoked for the function. So, convert the service to a macro and use a generic name (same as that used in Linux for some consistency). While at that, also add a data barrier which is necessary as per recommendation. While at this, smc #0 is maintained as handcoded assembly thanks to various gcc version eccentricities, discussion thread: http://marc.info/?t=142542166800001&r=1&w=2 Signed-off-by: Nishanth Menon <nm@ti.com> Tested-by: Matt Porter <mporter@konsulko.com> Reviewed-by: Tom Rini <trini@konsulko.com>
