Increase VM memory size

[lzSun]

hello,
I have written an email  about to increase the tz_vmm demo's memory size before, but haven't get any answer yet. The thing is, I want to increase the memory size that linux in the normal world can use. During these days, I found the related file which is at
" /genode/repos/base-hw/include/spec/imx53/drivers/trustzone.h " . In this file I found the NONSECURE_MEMORY_SIZE = 256*1024*1024. So I increase this size to 512*1024*1024, however, when the system booting, it print the error message like:
[init -> tz_vmm] Start virtual machine ...
[init -> tz_vmm] Error: failed to handle data abort

Did I missed something ? Any help will be grateful, thanks a lot!
