Hi Joonsoo, linaro version of QEMU has support for n900 machine. For
more information how to prepare & run kernel image see this email:
https://lists.denx.de/pipermail/u-boot/2015-January/200171.html
(instead u-boot.bin you would supply kernel's zImage)

But QEMU does not support HS mode, so there is probably no secure ram.
IIRC smc instructions should not be used in normal GP mode.
