The ColdFire 5207 and 5208 CPUs have fixed peripheral addresses. They do not use the setable peripheral address registers like the MBAR and IPSBAR used on many other ColdFire parts. Don't use fake values of MBAR and IPSBAR when using peripheral addresses for them, there is no need to. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
