Not true. This board is not manufactured by Freescale, so you should
not use the 'fsl,' prefix. Use your companies name or stock ticker
symbol instead.

This doesn't look right. The local bus is not board specific; it is
SoC specific. So this should be:
compatible = "fsl,mpc5121-localbus", "simple-bus";
