What cores do those chip use ? Any reason why one couldn't build a
kernel that boots those chips -and- chrp,pmac,etc... in one image ?

If that is the case, then your initcall will incorrectly be called on
platforms that don't need it.

I think what we need to do is to define a mecanism for board initcalls.

Something like board_xxx_initcall(boardname, function);
