This is not a ten64 device, but just component of the SoC, right?
Regular NXP LPC804 Cortex-M0 which you just program with different firmware.

Basically this means you describe the firmware in Devicetree...

Rob,

What are the guidelines for generic co-processors (some Cortex-M)
exposing just I2C line and nothing more? Do we want to describe the
actual firmware running there?

Best regards,
Krzysztof
