As far as I understand, I can enable secure memory on the simulator by setting
daughterboard.secure_memory=1. That way the model partitions SRAM and DRAM into
secure and non-secure memory and marks Boot ROM as secure memory. With that
configuration the VE memory map changes as described here
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0423m/CHDJFJHF.html
and shown in Table 6.2. If I enable this option then I don't seem to be able
to boot UEFI anymore. I have placed the UEFI binary
RTSM_VE_CORTEX-A15_MPCORE_EFI.fd into the flash loader 0. But it doesn't boot
and I don't get an error either. It just doesn't do anything. Is there anything
else I need to do in order to boot with the secure_memory option set?
Thanks,
Nicola
