Today though out of 40KB of non secure SRAM on OMAP4
we cannot use more than 32KB of SRAM in EMU devices
because of romcode restrictions.

OMAP5 is not a problem where we have sufficient
Non SECURE SRAM.

Just to understand, are we now required to
introduce #error macro in OMAP4 to get this through ?

Thanks,
