You could examine the relevant arch/arm/mm/proc-*.S file and modify the value passed back in for the control register in r0 (the function should be called something like xxxx_setup, and it will have the control register bits documented in groups of 4, eg WCAM). You want to ensure the W and C bits are clear. _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm http://www.arm.linux.org.uk/armlinux/mailinglists.php Please visit the above addresses for information on this list.
