bsh: imx8mn-smm-s2/pro: Add iMX8MN BSH SMM S2 boards
Introduce BSH SystemMaster (SMM) S2 board family, which consists of:
iMX8MN SMM S2 and iMX8MN SMM S2 PRO boards.
Add support for iMX8MN BSH SMM S2 board:
- 256 MiB DDR3 RAM
- 512MiB Nand
- USBOTG1 peripheral - fastboot.
- 100Mbit Ethernet
Add support for iMX8MN BSH SMM S2 PRO board:
- 512 MiB DDR3 RAM
- 8 GiB eMMC
- USBOTG1 peripheral - fastboot.
- 100Mbit Ethernet
