From 6303671189b085f2212dd1de8349422a725eb5cf Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Thu, 25 Jun 2020 17:20:32 -0600 Subject: security/vboot: Allow files to go into only RW-A or RW-B region The AMD firmware package created by amdfwtool contains pointers to the various binaries and settings. This means that we need different copies of the package in each region. This change allows for the different files in each of the 3 vboot regions. BUG=b:158124527 TEST=Build trembyle; see the correct versions of the files getting built into the RW-A & RW-B regions.
