From 61f826bdf1f6850b88313c83620ee436ca1313cf Mon Sep 17 00:00:00 2001 From: Tony Huang Date: Mon, 6 May 2024 16:50:04 +0800 Subject: mb/google/ovis/var/deku: Set PsysPL2 value to 178W Adjust setting as recommended by power team. Add ramstage.c in Makefile.inc to set psys_pl2_watts in variant_devtree_update(). Also copy CPU power limit values from ovis baseboard.
