rpmsg is a protocol. What's the h/w block?
On Linux side this driver is a virtual driver, it is running on Arm Cortex-A core. The h/w block is controlled by another core (cortex-M core). so this driver actually doesn't touch any hardware, it just does configuration for rpmsg channel. fsl,version: There are maybe different image running on M core, this is the image version, different image has different function.
To answer Rob's question: the hardware block that handles these messages is the Message Unit block.
