Samuel,
The VExpress EMM memory map will likely be used by many actual ARM devices in the future while the the ELT one will not be.

I used this one, since I don't have the required bootloader 'boot_emm.arm'.

You will need a different kernel, I have a 3.2 kernel at http://www.eecs.umich.edu/**mevbench/downloads.html [1]<http://www.eecs.umich.edu/mevbench/downloads.html [2]>that I am currently using.
