From dd32a31fbafafb6fa3dd1dc342884ffe88a7aa04 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 7 Mar 2013 23:15:06 -0600 Subject: coreboot: add vboot_handoff to coreboot tables The vboot_handoff structure contians the VbInitParams as well as the shared vboot data. In order for the boot loader to find it, the structure address and size needs to be obtained from the coreboot tables.
