Amarula Solutions has partnered with Engicam Srl and started a project
to push Engicam SOM’s and Carrier board’s BSP onto Mainline U-Boot,
Linux Kernel, Yocto/Buildroot, and Multimedia Open source projects.

We have supported PX30-Core in Mainline as posted before
`PX30-Core <https://wiki.amarulasolutions.com/news/301020.html>`_, now
we have another project-based `STMicroelectronics <https://www.st.com/content/st_com/en.html>`_
STM32MP1 SoM, `Engicam MicroGEAM STM32MP1 <https://www.engicam.com/vis-prod/101358>`_

For this specific SoM, Engicam is providing a `Capacitive Carrier board <https://www.engicam.com/vis-prod/101504>`_
and a `7" LVDS interfaced Open Frame board <https://www.engicam.com/vis-prod/101296>`_

Now, both these combinations are running Linux-5.10 and U-Boot-2021-01-rc2
and ready to send upstream patches.
