    Subject[PATCH v8 2/3] dts: zynqmp: add properties for TCM in remoteproc
    Date
    Add properties as per new bindings in zynqmp remoteproc node
    to represent TCM address and size.

    This patch also adds alternative remoteproc node to represent
    remoteproc cluster in split mode. By default lockstep mode is
    enabled and users should disable it before using split mode
    dts. Both device-tree nodes can't be used simultaneously one
    of them must be disabled. For zcu102-1.0 and zcu102-1.1 board
    remoteproc split mode dts node is enabled and lockstep mode
    dts is disabled.
