Beacon EmbeddedWorks is releasing a devkit based on the i.MX8M Nano SoC consisting of baseboard + SOM.
The kit is based on the same design as the Beacon dev kit with the i.MX8M Mini.

+Get the DDR firmware +==================== +$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.5.bin
There is a newer version of DDR firmware available from NXP: https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
It is also aligned with imx_5.4.47_2.2.0 ATF release, so for completeness purposes I would recommend you to include the updated link into README file.
Yocto meta-freescale layer is already using this firmware version for mx8m series [1], and it is operable.
I believe it would be beneficial to recommend users to pull the latest version available.
