 * Default secure signed bootloader (Nokia X-Loader) does not enable L3 firewall
 * for omap AES HW crypto support. When linux kernel try to access memory of AES
 * blocks then kernel receive "Unhandled fault: external abort on non-linefetch"
 * and crash. Until somebody fix omap-aes.c and omap_hwmod_3xxx_data.c code (no
 * crash anymore) omap AES support will be disabled for all Nokia N900 devices.
 * There is "unofficial" version of bootloader which enables AES in L3 firewall
 * but it is not widely used and to prevent kernel crash rather AES is disabled.
 * There is also no runtime detection code if AES is disabled in L3 firewall...
