Subject: m68knommu: make 54xx UART platform addressing consistent
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bbbeeaf2f74b634c95af3492e4958e752966eaa5;p=deliverable%2Flinux.git

m68knommu: make 54xx UART platform addressing consistent

If we make all UART addressing consistent across all ColdFire family members
then we will be able to remove the duplicated plaform data and use a single
setup for all.

So modify the ColdFire 54xx UART addressing so that:

. UARTs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used
