From 4c7924fb905b02323ff6d9d20f370892615dccfa Mon Sep 17 00:00:00 2001 From: Julien Massot Date: Fri, 22 Oct 2021 14:21:01 +0200 Subject: soc: renesas: rcar-rst: Add support to set rproc boot address R-Car Gen3 SoC series has a realtime processor, the boot address of this processor can be set thanks to CR7BAR register of the reset module. Export this function so that it's possible to set the boot address from a remoteproc driver. Also drop the __initdata qualifier on rcar_rst_base, since we will use this address later than init time.

This patch adds a new compatible string for the RZ/G2L family so that the timing values on RZ/G2L can be adjusted.
