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.
