From b0c302fd79c19d6a01af64fc798bc7be1c1bb59c Mon Sep 17 00:00:00 2001 From: Vadim Bendebury Date: Mon, 28 Jul 2014 16:03:07 -0700 Subject: Publish the board ID value in coreboot table, when configured Board ID value is usually of interest to bootloaders. Instead of duplicating the board ID discovery code in different bootloaders let's determine it in coreboot and publish it through coreboot table, when configured.
