From 35597435d023150d847ec11019cb19cba29397bf Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sun, 1 Nov 2020 22:39:15 +0100 Subject: mb/purism/librem_cnl: Set SaGv to FixedHigh Since the Librem Mini does not run on battery power, SaGv has little benefits and noticeably slows down testing, since memory training is run twice. Disabling SaGv cuts the 30-second cold boot time in half.
