[PATCH 00/16] bootstd: Improve ChromiumOS support

[Simon Glass]

The ChromiumOS bootmeth is fairly basic at present. It is able to boot
only x86 kernels and contains quite a few hard-coded offsets.

This series tidies it up by bringing in some vboot structures and adding
support for ARM.

It adds a few more features to bootstd, including display of x86 setup
information.

So far this does not actually boot correctly on any ARM Chromebook:

   jerry - hangs when booting kernel
   bob - Bad Linux ARM64 Image magic! with lz4-compressed kernel

Further work can address these issues.
