26 network ports to create functional objects/devices such as network
29 which DPAA2 software drivers use to operate on DPAA2 objects.
71 DPIO objects.
76 The section provides a brief overview of some key DPAA2 objects.
77 A simple scenario is described illustrating the objects involved
84 types of DPAA2 objects.  In the example diagram below there
85 are 8 objects of 5 types (DPMCP, DPIO, DPBP, DPNI, and DPMAC)
105 of the DPRC, discover the hardware objects present (including mappable
118 Hardware objects can be created and destroyed dynamically, providing
119 the ability to hot plug/unplug objects in and out of the DPRC.
124 All objects in a container share the same hardware "isolation context".
129 DPRCs can be defined statically and populated with objects
138 utilizing multiple hardware objects.  Each object provides specialized
139 functions. Groups of these objects are used by software to provide

268 In the case of DPAA2 devices/objects, all objects in the
281 types of DPAA2 objects.  It is functionally similar to a plug-and-play
285 scenario and the objects bound to each driver.  A brief description
348 The DPRC driver is bound to DPRC objects and does runtime management
355 Certain objects such as DPMCP and DPBP are generic and fungible,
363 and those objects are bound to the allocator when the bus is probed.
364 The allocator maintains a pool of objects that are available for
369 The DPIO driver is bound to DPIO objects and provides services that allow
