[Dario Binacchi <dario.binacchi@amarulasolutions.com>]

From: Michael Trimarchi <michael@amarulasolutions.com>

BSH SMM S2 PRO (SystemMaster S2 Pro) Board is an add-on board which
provide input and output interfaces to a dedicated carrier board. It is
designed mainly to provide graphical/video and connectivity interfaces
to the appliance.

Board support package includes the following components:
- mainline Linux kernel 5.18
- mainline U-Boot 2022-07-rc2
- Default packages from buildroot

https://www.apertis.org/reference_hardware/imx8mn_bsh_smm_s2pro_setup/

Add Ariel D'Alessandro and Dario Binacchi as co-maintainer, we work
together on platform mainline

Build and tested using:
docker pull registry.gitlab.com/buildroot.org/buildroot/base:20220105.2314

+i.MX8MN BSH SMM S2 PRO
+======================
+
+How to build it
+---------------
+
+Configure buildroot:
+
+  $ make imx8mn_bsh_smm_s2_pro_defconfig
+
+Change settings to fit your needs (optional):
+
+  $ make menuconfig
+
+Compile everything and build the rootfs image:
+
+  $ make
+
+
+Result of the build
+-------------------
+
+After building, the output/images directory contains:
+
+  output/images/
+    ├── bl31.bin
+    ├── Image
+    ├── flash.bin
+    ├── ddr3*
+    ├── rootfs.ext2
+    ├── rootfs.ext4 -> rootfs.ext2
+    ├── rootfs.tar
+    ├── sdcard.img
+    ├── u-boot.bin
+    ├── u-boot-nodtb.bin
+    └── u-boot-spl.bin
+
+
+Preparing the board
+-------------------
+
+Plug the USB type A to micro B cable into the USB Debug
+Connector (DBG UART). Use serial port settings 115200 8N1
+to access the debug console.
+
+Plug another USB type A to micro B cable into the USB-OTG
+Connector (USB1). This connection is used to flash the board
+firmware using the Freescale/NXP UUU tool.
+
+Connect the power supply/adaptor to the DC Power Jack (labelled
++5V).
+
+
+Flashing the emmc card image
+----------------------------
+
+Power up the board by switching on the Power ON Switch, which is
+placed right next to the DC Jack.
+
+Enter the following U-Boot commands on the debug serial console:
+
+  $ fastboot usb 0
+
+Flash the images on eMMC. On your computer, run:
+
+  $ board/bsh/imx8mn-bsh-smm-s2-pro/flash.sh output/
+
+
+Booting the board
+-----------------
+
+By default the bootloader will search for the first valid image,
+starting with the internal eMMC.
