Actually it only uses XC_PAGE_SIZE and the endianness is the host
endianness.

Are you talking about introducing accel=xen to Wei's target-null?
I guess that would work OK.

On the other hand if you are thinking of avoiding the introduction of a

multiple architectures? How would you avoid the compilation of all the
unnecessary emulated devices?
