eb59195473 Refactor crossystem to move x86-specific implementation to its own file.
This should be ready for the ARM team to pick up and work on.  I added
a placeholder ARM implementation file, though it's not hooked up in
the Makefile yet.

As soon as you implement the VbNvStorage APIs, all the related
crossystem commands will start working.  Ditto for VbSharedData.

The params which x86 gets from ACPI you'll need to get from u-boot
somehow, probably via your own kernel driver.

60bcbe3cd4 New tools to help debug vboot failures.
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.

TEST=manual

To test, obtain a root shell, and run dev_debug_vboot. You should see lots
of useful information go by.

abf0550458 Switch to using .vbprivk for signing everything now.
This makes it much simpler to keep track of what we're doing.

vbutil_key can now wrap both .keyb and .pem keys. It figures out which is
which by trying both and just using the one that works.

vbutil_keyblock and vbutil_kernel now use .vbprivk files for signing.

replace debug() with VBDEBUG(()) in host-side sources, too.

rename PrivateKeyRead to PrivateKeyReadPem

Add real PrivateKeyRead and PrivateKeyWrite for .vbprivk files.
