      arm: dts: k3-j7200-main: Add MAIN domain R5F cluster nodes · 3f7e032f
      Suman Anna authored and Lokesh Vutla's avatar Lokesh Vutla committed
      
      The J7200 SoCs have 2 dual-core Arm Cortex-R5F processor (R5FSS)
      subsystems/clusters. One R5F cluster is present within the MCU
      domain (MCU_R5FSS0), and the other one is present within the MAIN
      domain (MAIN_R5FSS0). Each of these can be configured at boot time
      to be either run in a LockStep mode or in an Asymmetric Multi
      Processing (AMP) fashion in Split-mode. These subsystems have 64 KB
      each Tightly-Coupled Memory (TCM) internal memories for each core
      split between two banks - ATCM and BTCM (further interleaved into
      two banks). The TCMs of both Cores are combined in LockStep-mode
      to provide a larger 128 KB of memory.
      
      Add the DT node for the MAIN domain R5F cluster/subsystem, the two
      R5F cores are added as child nodes to the main cluster/subsystem node.
      The cluster is configured to run in Split-mode by default, with the
      ATCMs enabled to allow the R5 cores to execute code from DDR with
      boot-strapping code from ATCM. The inter-processor communication
      between the main A72 cores and these processors is achieved through
      shared memory and Mailboxes.
