| * Allocate memory and initialize the FPA pools using memory |

| * controlled by the cvmx-config.h header file. Specifying |
| * zero for any parameter will cause that FPA pool to not be |
| * setup. This is useful if you aren't using some of the |

| * @packet_buffers: |
| * Number of packet buffers to allocate |
| * @work_queue_entries: |
| * Number of work queue entries |
| * @pko_buffers: |
| * PKO Command buffers. You should at minimum have two per |
| * each PKO queue. |
| * @tim_buffers: |
| * TIM ring buffer command queues. At least two per timer bucket |
| * is recommened. |
| * @dfa_buffers: |
| * DFA command buffer. A relatively small (32 for example) |
| * number should work. |
| * Returns Zero on success, non-zero if out of memory |
