This new version adds a bunch more output, displays the TPM rollback version
values (if it can; Cr-48 doesn't export this info through crossystem), looks
for and validates all kernels on all devices, etc.
It also add some command-line arguments to use to examine files containing
BIOS, kernel, and disk images.

Boot, wait a minute or so, then log in and go to chrome://system
Click the Expand button for "verified boot". You should see a bunch of
useful text describing the firmware and kernel partitions.
I tried this on Cr-48, Stumpy, and Kaen.

The script needs to use proper device names when looking for
'hard drive' and USB storage. This change makes these names
platforms specific. Another change is to look for the USB device
when running off SSD and include it in report if found.

off USB or SSD), observed expected results reported, for instance
when running off USB stick on Kaen with a valid system installed

Two things here: Use mktemp to create a unique and new temporary directory
to work in, and copy the published log file to a known path in a way that
can't be redirected with symlinks.
There are also a couple of minor tweaks to cleanup a little bit rot in the
information that the script provides.

Boot, wait 60 seconds, look for "/tmp/debug_vboot_noisy.log". It should
exist and contain useful and interesting data.

* Display only the synopsis on stdout
* Keep a verbose log of all activity in the scratch directory.
* Add more checks
* Providing a directory argument will use the images found there instead of
trying to extract them from the system (for use on host machines).

Get a root shell and run "dev_debug_vboot". You should see nicer output.

This adds some tools to help us figure out why a particular kernel isn't
booting. Often we suspect it's because it was signed with the wrong keys, or
has flags restricting its use to certain boot modes. This change adds some
tools to extract and display all the keys from the BIOS, and try them on the
various kernels. We also display the sha1sum of all the keys we find, to
make comparing them easier.
