Hi Bjorn,

As discussed during Linaro connect, could you review/accept these 2 
patches providing da to pa translation mechanism for firmware loading?
I agree a central solution will better, but today all drivers are based 
on this mechanism.
Could we move on this solution to complete remoteproc support for B2260 
96board?

Regards,
Loic
