[RFC,0/1] Add support for setting Cortex R7 boot address

Message

Hi,
I plan to submit a small driver to remoteproc subsystem in order
to manage the Cortex R7 found on various SoCs of the R-Car Gen3
SoC series.

Enabling this processor from the remoteproc subsystem requires to:
- loading a firmware to a RAM area.
- setting the boot address thanks to CR7BAR register
- enable power domains
- deassert CR7 reset

The goal here is to export a function from rcar-rst.c to allow a
a remoteproc driver to set this boot address.

I'm not so much used to manipulate init data so don't hesitate to
comment.

Thanks !
