Here, only mac-address and local-mac-address are supported. So, would the
code below do the job?

  local-mac-address:
    $ref: ethernet-controller.yaml#/properties/local-mac-address

  mac-address:
    $ref: ethernet-controller.yaml#/properties/mac-address

When a property is specific to a bus, I would have like to explicitly
say it. That's why I redefined the description.

This file is not a firmware. It mainly contains data related to the
antenna. At the beginning, this property has been added for
development. With the time, I think it can be used to  have one disk
image for several devices that differ only in antenna.

I am going to remove the part about development/debug purpose.

I think I need to specify "additionalProperties: true" since the user can
also use properties defined for the SPI devices.

In fact, I would like to write something like:

    allOf:
        $ref: spi-controller.yaml#/patternProperties/^.*@[0-9a-f]+$/properties
