From b34de93153cd937db841b2dd39d42087ee44902e Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Wed, 10 Apr 2019 18:43:56 -0700 Subject: ec/google/wilco: Support board_id with EC provided ID The EC can return a board ID value similar to the Chrome EC. In order to use this for the board version returned by SMBIOS this commit implements the board_id() function for mainboards that use this EC. BUG=b:123261132 TEST=Check /sys/class/dmi/id/board_version to see that it is reflecting the value that the EC provides.
