Kill our own hand-rolled (and somewhat flawed) devpath_str in favor of the recently added efi_devpath_str in libefi. This gives us much better names at the expense of not being able to debug on EFI 1.2 machines (since the UEFI protocol efi_devpath_str depends on was added in UEFI 2.0). However, this isn't the first thing that requires newer than EFI 1.2, so it's quite possible that this doesn't change the universe of machines we can EFI boot from. This will now give us the full UEFI path, even for devices we don't yet know about. More importantly, it gives us the full HD(...) part of the path, which is sufficient by itself to locate disks that follow the rules (dd one disk (but not partition) to another still needs the rest of the path to disambiguate, but that isn't following the rules that require every GPT table to have globally unique GUIDs for every partion). This also has the side effect of shrinking boot1.efi by ~3k. Sponsored by: Netflix

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
