crossystem: introduce a new main firmware type, 'netboot'
We need to be able to tell when a ChromeOS machine was brought up
using netboot. This condition will be communicated from firmware using
the BINF.3 ACPI object (upcoming u-boot change).
BUG=chrome-os-partner:7952
TEST=manual
. boot a ChromeOS machine using the updated firmware and examine the
main firmware type reported by crossystem:
localhost ~ # echo $(/var/crossystem mainfw_type)
netboot
