Currently seeing the following error when running runqemu on qemuarmv5:
runqemu - ERROR - Failed to run qemu: qemu-system-arm: versatilepb: memory size must not exceed 256MB

This is due to the memory size being set to 512 instead of the max
allowable of 256. Limit to this and everything is happy.

Grepping for QB_MEM suggests there are other images which need the
same fix. Maybe good to fix all of them at once rather than one at a
I do not know if other machines have this same issue with qemu, and
this is probably not the best way to resolve this (as I really think
this should be part of the machine config file, and have runqemu be
smarter logic about setting the memory size). I can open a bug in
bugzilla and get back to it later.
perhaps we should define MAX_MEMORY to define this limit for every
emulated machine and present a diagnostic if QB_MEM exceded MAX value
I'm making an assumption that QB_MEM is the max. If we simply added
sanity checks to the places where it is overridden, there would be no
problems. It shouldn't be too hard to do, but based on other comments
I think it's best to abandon this series and simply remove qemuarmv5.
