From 30974bc2f5f4764425e69256782cca03b290c4f4 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 20 Mar 2014 14:28:17 -0500 Subject: vboot: allow for non-memory-mapped VBOOT regions Depending on the platform the underlying regions vboot requires may not be accessible through a memory-mapped interface. Allow for non-memory-mapped regions by providing a region request abstraction. There is then only a few touch points in the code to provide compile-time decision making no how to obtain a region. For the vblocks a temporary area is allocated from cbmem. They are then read from the SPI into the temporarily buffer. BUG=chrome-os-partner:27094 BRANCH=None TEST=Built and booted a rambi with vboot verification.
