Finding a similar reference board already supported

For some projects, it is easy to understand which reference board is closest to the one being included. It is common that in early stages, the project starts using a reference board, and when that is the case, the reference board is obvious; is only a matter of searching Supported Machines to check if this is supported.

In the other case when it is not an obvious answer, the task of searching for the closest reference board is looking for what reference board shares the same SoC which is usually described in the machine configuration file by the tag @SOC.

If searching for @SOC through the meta-layers brings more than one machine with the same SoC used on the project, the suggestion here is to prefer the machine from the SoC vendor.

The SoC vendor is usually present on the tag @NAME in the machine configuration file.

In this document, there are several examples where i.MX8M Mini EVK is used as a reference board.
