It is still the problem with the peripherals. First, these are still 
vendor specific ( position of address, features and bit positions) and 
second the broadly used pointer addressing of the config areas of these 
and the CMSIS. For CMSIS I don't see any problem to use this pointer 
addressing as the functions for setting up the Core are encapsulated.

But in general there is just writing abstractions for the peripherals 
and nothing else to support CortexM from any supplier.
