Ah, thanks :).

Anyone have any objection to the following:  each of these controllers
should have compatible properties listing 3 string, first, a specific
version for the CPU in question (e.g "ibm,sdram-440gp"), then a string
based on the type as listed below, finally "ibm,sdram-4xx".

Seem reasonable?
