Changed against the original Freescale code (and against clocklib for example): - clock rate is always calculated whenever one ask for the current rate. (means no "rate" member in the clock structure). So switching the PLL base frequency will propagate immediately to all other clocks that are depending on this frequency. TODO: - Check if the i.MX21 CPU can share the same code.

It is as generic as possible in order to support any kind of baseboard. Note: This CPU module implementation can't work without a baseboard support. Baseboard support can be added by the PCM-970 (included in this patch stack) or any custom variant.

This patch adds support for the hardware. This code is only an empty stub; it is filled up with functionality in a later patch series.
