/*
|
|
* Stream IDs on Chassis-2 (for example ls1043a, ls1046a, ls1012) 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 DPAA1 devices.
|
|
*
|
|
* This partitioning can be customized in this file depending
|
|
* on the specific hardware config:
|
|
*
|
|
* -non-PCI legacy, platform devices (USB, SDHC, SATA, DMA, QE etc)
|
|
* -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)
|
|
*
|
|
* -DPAA1
|
|
* - Stream ids for DPAA1 use are reserved for future usecase.
