I used to make use of AXI-GPIO's in order to connect a couple (4x32bit to be specific) of status and control registers from the VHDL code to the Microblaze. Now that the system scales up and there are three or four more 32bit registers added, that the microblaze has to deal with, this quick and simple solution does not seem to be right any more (Or is it?).
As far as I know, a AXI - BRAM Controller could be used to break the AXI Interface down to the minimum and allow interfacing registers.
I would really like to keep this as simple as possible. Is there another approach that I am not aware of?

@balkris: Your link only describes how to set up AXI-GPIO. This is how the register interface of the current system looks like. It just does not feel right to instantiate 4 of them in order to deal with the registers...
