From fa7e6b8c031702a2ad31018fb00dfa75e427cbb7 Mon Sep 17 00:00:00 2001 From: John Su Date: Thu, 20 Apr 2023 14:35:35 +0800 Subject: mb/google/skyrim/var/markarth: Change to read the eMMC clkreq instead Because WD SSD drive isn't holding the clock low for some reason. So we change to read eMMC clkreq signal instead. BRANCH=none BUG=b:278495684 TEST=emerge-skyrim coreboot chromeos-bootimage and verify ok.
