/* 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
* ----------------------------
