Most of them can NOT coexist in one kernel due to address space layout
differences, firmware differences etc. and users can not be expected to
know the details nor is it realistic to make a generic kernel for MIPS.
So as you say there should only one be selectable.

Patches will be accepted :-) Actually in the past things were slightly
more as you were suggesting but the code was fairly spagetty-like with the
intension to redo it somewhen.
