The PIT hardware timer module used in some ColdFire CPU's is not always addressed relative to an IPSBAR register. Parts like the ColdFire 5207 and 5208 have fixed peripheral addresses. So lets not define the register addresses of the PIT relative to an IPSBAR definition. Move the base address definitions into the per-part headers. This is a lot more consistent since all the other peripheral base addresses are defined in the per-part header files already. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
