2 * MikroTik SPI-NOR RouterBOARDs support
3 *
4 * - MikroTik RouterBOARD mAP 2nD
5 * - MikroTik RouterBOARD mAP L-2nD
6 * - MikroTik RouterBOARD 941L-2nD
7 * - MikroTik RouterBOARD 951Ui-2nD
8 * - MikroTik RouterBOARD 952Ui-5ac2nD
9 * - MikroTik RouterBOARD 962UiGS-5HacT2HnT
10 * - MikroTik RouterBOARD 750UP r2
11 * - MikroTik RouterBOARD 750P-PBr2
12 * - MikroTik RouterBOARD 750 r2
13 * - MikroTik RouterBOARD LHG 5nD
14 * - MikroTik RouterBOARD wAP2nD
15 * - MikroTik RouterBOARD wAP G-5HacT2HnDwAP (wAP AC)
16 *
17 * Preliminary support for the following hardware
18 * - MikroTik RouterBOARD cAP2nD
19 * Furthermore, the cAP lite (cAPL2nD) appears to feature the exact same
20 * hardware as the mAP L-2nD. It is unknown if they share the same board
21 * identifier.
