Thanks for the review. Will take into account in the next revision.
In case of am62d, I could reuse the same yaml file as am62a. That should 
reduce the patch size at-least.
For a generic solution across boards, we need to have a right usage 
model something that will need more discussion. Same with the case of 
ddr config here.
