Subject: common/dpaax: move OF library from DPAA bus
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8c83f28cc8a4dc7ee0fab676051dd483695d4140;p=dpdk.git

common/dpaax: move OF library from DPAA bus

This code is being shared by more than 1 type of driver.
Common is most appropriate place for it.
