I have an i.MX27 and i.MX31 board here. Question is, what kind of = CPU/architecture support you are using for i.MX21? The one from arch/arm/im= x? = Or something from arch/arm/mxc3, arch/arm/plat-mxc? So now we have a few (nearly working) implementations. What should be used? = The implementations from soc/imx or from soc/fsl? Juergen -- = Dipl.-Ing.
