armv8: fsl-lsch3: rename ls2080a_stream_id.h to stream_id_lsch3.h
The stream ID allocation for Chasis 3.0 devices can be shared among LS1088, LS2088 and LS2080. Signed-off-by: Bharat Bhushan <Bharat.Bhushan@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>

- * 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 partitioning can be customized in this file depending
- * on the specific hardware config:
- *
- * -non-PCI legacy, platform devices (USB, SD/MMC, SATA, DMA)
- * -all legacy devices get a unique stream ID assigned and programmed in
- * their AMQR registers by u-boot
- *
- * -PCIe
- * -there is a range of stream IDs set aside for PCI in this
- * file. U-boot will scan the PCI bus and for each device discovered:
- * -allocate a streamID
- * -set a PEXn LUT table entry mapping 'requester ID' to 'stream ID'
- * -set a msi-map entry in the PEXn controller node in the
- * device tree (see Documentation/devicetree/bindings/pci/pci-msi.txt
- * for more info on the msi-map definition)
- *
- * -DPAA2
- * -u-boot will allocate a range of stream IDs to be used by the Management
- * Complex for containers and will set these values in the MC DPC image.
- * -the MC is responsible for allocating and setting up 'isolation context
- * IDs (ICIDs) based on the allocated stream IDs for all DPAA2 devices.
- *
- * On ls2080a SoCs 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 // privilege bit
- * BMT[17] 8 // bypass translation
- * VA[16] 7 // reserved
- * [15] - // unused
- * ICID[14:7] - // unused
- * ICID[6:0] 6-0 // isolation context id
- * ----------------------------
