/*
* Stream IDs on NXP Chassis-3 (for example ls2080a, ls1088a, ls2088a)
* 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)
* -set a iommu-map entry in the PEXn controller node in the
* device tree (see Documentation/devicetree/bindings/pci/pci-iommu.txt
* for more info on the iommu-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.
* -u-boot will fixup the iommu-map property in the fsl-mc node in the
* device tree (see Documentation/devicetree/bindings/misc/fsl,qoriq-mc.txt
* for more info on the msi-map definition)
* -the MC is responsible for allocating and setting up 'isolation context
* IDs (ICIDs) based on the allocated stream IDs for all DPAA2 devices.
*
* - ECAM (integrated PCI)
* - U-Boot applies the value here to HW and does DT fix-up for both
* 'iommu-map' and 'msi-map'
*
* On Chasis-3 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
* ----------------------------
