Hello Rahul, I'm happy to see that you're interested in RPMI support in U-Boot. Can you share with us the context in which you developed those patches? i.e., what hardware are you using and how is the "mpxy" command used. Is "mpxy" mostly just for debugging or is it expected that a bootscript would initialize the platform with calls to "mpxy"?
