/*
* MikroTik SPI-NOR RouterBOARDs support
*
* - MikroTik RouterBOARD mAP 2nD
* - MikroTik RouterBOARD mAP L-2nD
* - MikroTik RouterBOARD 911-2Hn (911 Lite2)
* - MikroTik RouterBOARD 911-5Hn (911 Lite5)
* - MikroTik RouterBOARD 931-2nD (hAP mini)
* - MikroTik RouterBOARD 941L-2nD
* - MikroTik RouterBOARD 951Ui-2nD
* - MikroTik RouterBOARD 952Ui-5ac2nD
* - MikroTik RouterBOARD 962UiGS-5HacT2HnT
* - MikroTik RouterBOARD 750UP r2
* - MikroTik RouterBOARD 750P-PBr2
* - MikroTik RouterBOARD 750 r2
* - MikroTik RouterBOARD LHG 5nD
* - MikroTik RouterBOARD wAP2nD
* - MikroTik RouterBOARD wAP G-5HacT2HnDwAP (wAP AC)
* - MikroTik RouterBOARD wAP R-2nD
*
* Preliminary support for the following hardware
* - MikroTik RouterBOARD cAP2nD
* Furthermore, the cAP lite (cAPL2nD) appears to feature the exact same
* hardware as the mAP L-2nD. It is unknown if they share the same board
* identifier.
