This is the Chrome OS bootstub that handles the handoff from our custom BIOS
to the kernel.

The Makefile was adapted from sample code in the gnu-efi library (GPLv2 or
later).

The trampoline.S code was adapted from grub v1.97 (GPLv3 or later).

The bootstub.c code was written from scratch, although code from both grub
and elilo v3.7 (GPLv2 or later) was referred to for examples.

Accordingly, the bootstub code as a whole is subject to the license terms of
the GPLv3 (or later).

The authors are grateful to the above mentioned projects for their
contributions to the free software community.
