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 * - MikroTik RouterBOARD LHG 5nD
10 *
11 * Preliminary support for the following hardware
12 * - MikroTik RouterBOARD wAP2nD
13 * - MikroTik RouterBOARD cAP2nD
14 * - MikroTik RouterBOARD mAP2nD
15 * Furthermore, the cAP lite (cAPL2nD) appears to feature the exact same
16 * hardware as the mAP L-2nD. It is unknown if they share the same board
17 * identifier.
