From f56db262e46d3368ee4e5c9e19797853cab382cd Mon Sep 17 00:00:00 2001 From: Salvatore Bellizzi Date: Wed, 7 Mar 2018 14:56:43 +0100 Subject: platform/chrome: cros_ec_lpc: Add support for Google devices using custom coreboot firmware This patch adds generic device information to the DMI table of the cros_ec_lpc driver, needed for Chromebooks/boxes using a custom coreboot firmware. The DMI info would not contain "Google_*" as BIOS version string, instead the system vendor string would still be "GOOGLE", so this seems to be a reasonable match for every Chromebook/box running a custom firmware.
