    ARM: dts: am572x-idk-common: Add CMA pools and enable IPU & DSP rprocs · ac21a4a8
    Suman Anna authored
    The CMA reserved memory nodes have been added for all the IPU and DSP
    remoteproc devices in the am572x-idk-common.dtsi file that is common to
    both the AM572x and AM574x IDK boards. These nodes are assigned to the
    respective rproc device nodes, and all the IPU and DSP remote processors
    are enabled.
    
    The current CMA pools and sizes are defined statically for each device.
    The addresses chosen are the same as the respective processors on
    the AM57xx EVM board to maintain firmware compatibility between the
    two boards. The CMA pools and sizes are defined using 64-bit values
    to support LPAE. The starting addresses are fixed to meet current
    dependencies on the remote processor firmwares, and this will go
    away when the remote-side code has been improved to gather this
    information runtime during its initialization.
    
    An associated pair of the rproc node and its CMA node can be disabled
    later on if there is no use-case defined to use that remote processor.
