vpd: retrieve mac addresses and pass them to bootloader
Chrome OS devices firmware usually includes an area called VPD (Vital
Product Data). VPD is a blob of a certain structure, in particular
containing freely defined variable size fields. A field is a tuple of
the field name and field contents.
MAC addresses of the interfaces are stored in VPD as well. Field names
are in the form of 'ethernet_macN', where N is the zero based
interface number.
This patch retrieves the MAC address(es) from the VPD and populates
them in the coreboot table so that they become available to the
bootloader.
BUG=chrome-os-partner:32152, chromium:417117
TEST=with this and other patches in place the storm device tree shows
up with MAC addresses properly initialized.
