|
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, ...). |
