From 4f7a3614cd07acdb6855c32eea38e5585834ee24 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Wed, 20 Jan 2016 18:01:15 -0800 Subject: chromeos: Add timestamps to measure VPD read times This patch adds three timestamps to coreboot and the cbmem utility that track the time required to read in the Chrome OS Vital Product Data (VPD) blocks (RO and RW). It's useful to account for these like all other large flash accesses, since their size is variable. BRANCH=None BUG=None TEST=Booted Oak, found my weird 100ms gap at the start of ramstage properly accounted for.
