| /* Stream IDs on ls2080a devices are not hardwired and are |
| * programmed by sw. There are a limited number of stream IDs |
| * available, and the partitioning of them is scenario dependent. |
| * This header defines the partitioning between legacy, PCI, |
| * and DPAA2 devices. |
| * |
| * This partitiong can be customized in this file depending |
| * on the specific hardware config-- e.g. perhaps not all |
| * PEX controllers are in use. |
| * |
| * On LS2080 stream IDs are programmed in AMQ registers (32-bits) for |
| * each of the different bus masters. The relationship between |
| * the AMQ registers and stream IDs is defined in the table below: |
| * AMQ bit streamID bit |
| * --------------------------- |
| * PL[18] 9 |
| * BMT[17] 8 |
| * VA[16] 7 |
| * [15] - |
| * ICID[14:7] - |
| * ICID[6:0] 6-0 |
