Take a look at splash*.c , I believe that can be reworked into generic firmware loader , which you could then use here.
the devpart is hard coded in splash*.c. The function here is getting devpart info from DTS. So, is there any similar function in splash*.c? May be you can share more about your idea.
The generic loader could use some work of course ...
