Sure. No argument on separating CPU support and system support.
I thought Simon was asking how different the mmeye and the evbsh3
were: do they need separate ports and separate kernels, or
could/should we aim for one kernel that boots on both?

Which is about the same thing I'm wondering about QED5xxx-core
handheld devices and the hpc port.
