[U-Boot-Users] command for handling DDR ECC registers on MPC8349EE MDS board

Since this DDR memory controller is a feature of the SoC platform which is common to a few cpu's and many boards, what is the preferred way to add this new command to the other boards which could take advantage of it?

The list of boards include at least: mpc8540ads, mpc8560ads, cds/mpc8541cds, cds/mpc8555cds, and cds/mpc8548cds.
