From 40668e8b5fb9a9e07a3b1ddf334bd4e12a38525f Mon Sep 17 00:00:00 2001
From: Paul Kocialkowski <contact@paulk.fr>

Subject: [PATCH 5/8] vboot: Only initialize cparams once
Calling common_params_init multiple times in a row results in emptying cparams
each time, causing the GBB data to be lost as it is only read once (the first
time).
