  The CMDQ(COMMAND QUEUE) reads a set of commands from memory and then decodes commands and execute it. There are five actions as below:
    - Null: do nothing but execute next command.
    - Write: write RIU command to XARB.
    - Wait: wait for a specified bit of trigger bus and then execute next command.
    - Polling_eq: read RIU data and check specified bits. If it is equal, next command will be executed.
    - Polling_neq: read RIU data and check specified bits. If it is not equal, next command will be executed.
  These five commands have their own format and each command occupies 64 bits. Therefore, for command queue, a 128-bit MIU interface of this IP, two commands are placed at the same address

  The CMDQ execution mode we use is Ring-Buffer Mode. There are two address pointers, r and w, move around a given memory space, which is limited between start pointer and end pointer.
  Software part tells cmdq where is the current write address pointer(w), and cmdq will do the command sets that software writes.
  Once software finishes storing commands in memory, it needs write current write address pointer(sw_wr_mi_wadr) and generate a trigger(mov_cmd_ptr) to inform cmdq.
  If software wants to know where cmdq reads, the trigger signal, rd_mi_radr_trig, needs to send to cmdq to grab current read address pointer (rd_mi_radr).
  Note that current read address pointer does not represent all data that is behind current read address pointer is sent to cmdq.
