Currently we use hardcoded values of the MR registers that only work on the ECPIX-5. We should either:

set MR registers at compile time (leaner code, smaller ROM footprint)
allow loading MR registers from a struct of some sort (needs a bit more code but could allow for a single firmware image to work on multiple boards with different RAM chips)

This has been partially fixed in bae4da5, we now have to generate those MRx values.
