From 8c4674ee37c3446e7cf4dd81101e6eaa3d5fc690 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Thu, 26 Oct 2023 16:11:10 +0530 Subject: mb/google/{rex, ovis}: Introduce devicetree.cb for pre-prod SoC This patch introduces a dedicated devicetree.cb file for platforms built with pre-production SoC. This will help to keep the SoC configuration separate for platforms with ESx and QSx silicons. For example, the SaGv WP configuration is different between pre-production (aka ESx) and production (aka QSx) silicon. BUG=b:306267652 TEST=Able to build and boot google/rex4es.
