This document defines the bindings for the remoteproc component that loads and
|
|
|
|
|
boots firmwares on the Renesas R-Car family chipset.
|
|
|
|
|
R-Car gen3 family may have a realtime processor, this processor shares peripheral
|
|
|
|
|
and RAM with the host processor with the same address map.

List of phandles to the reserved memory regions associated with the

remoteproc device. This is variable and describes the memories shared with

the remote processor (e.g. remoteproc firmware and carveouts, rpmsg

vrings, ...).
