   2  *  MikroTik SPI-NOR RouterBOARDs support
   3  *
   4  *  - MikroTik RouterBOARD mAP L-2nD
   5  *  - MikroTik RouterBOARD 941L-2nD
   6  *  - MikroTik RouterBOARD 951Ui-2nD
   7  *  - MikroTik RouterBOARD 750UP r2
   8  *  - MikroTik RouterBOARD 750 r2
   9  *
  10  *  Preliminary support for the following hardware
  11  *  - MikroTik RouterBOARD wAP2nD
  12  *  - MikroTik RouterBOARD cAP2nD
  13  *  - MikroTik RouterBOARD mAP2nD
  14  *  Furthermore, the cAP lite (cAPL2nD) appears to feature the exact same
  15  *  hardware as the mAP L-2nD. It is unknown if they share the same board
  16  *  identifier.
