Subject: ARM: mv78xx0: Move to ID based window creation
X-Git-Tag: v3.12-rc1~115^2~15^2~31
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=c5d0ecc98ca94eb55eacda034a304d5d028d514a;p=~emulex%2Finfiniband.git

ARM: mv78xx0: Move to ID based window creation

With the introduction of the ID based MBus API, it's better
to switch to use it instead of the current name based scheme.

This will allow to deprecate the name based API, once every
user is removed.
