Then there will be a review for the new code. At the moment, this part
behaves as dead code.

Do you mean the same board files will be used ? I am not aware about a
board having two different SOCs. Probably (I say probably, we will see
whan the patches for a new board will be sent...) we will have a
different structure, as the MX53 have different setup as the MX51. In
the same way we have now a mx51evk and mx53evk.

Personally I find confusing if sometimes an #ifdef is used and the next
time #ifndef with the opposite CONFIG is taken, and both part of code
are compiled at the same time.

I let you decide.

Surely, you can add a patch to this patchset.
