Re: [PATCH 2/3] dt-bindings: net: Add support for J-Core EMAC

[D. Jeff Dionne]

Something like:

J-Core SoCs are assembled with an SoC generator tool from standard components.  An SoC has a ROM from soc_gen with a Device Tree binary included.  Therefore, J-Core SoC devices are designed to ‘just work’ with linux, but this means the DT entires are generic, slightly different than standard device tree practice.
