Hi Linus,

Does the following description sound good for you:
Firewall properties provide the possible firewall bus controller 
configurations for a device.
Bus firewall controllers are typically used to control if a hardware 
block can perform read or write operations on bus.
The contents of the firewall bus configuration properties are defined by 
the binding for the individual firewall controller device.
The first configuration 'firewall-0' or the one named 'default' is 
applied before probing the device itself.

Regards,
Benjamin
