Andrew Turner 698c14e189 Add a kernel variable to let the user to select their preferred order
between ACPI and FDT. This will be needed on machines with both, e.g. the
SoftIron Overdrive 3000. The kernel will accept one or more comma separated
values of either 'acpi' or 'fdt'. Any other values are skipped.

To set it the user can either set it on the loader command line, or
in loader.conf e.g. in loader.conf:
kern.cfg.order=acpi,fdt

This will try using ACPI then FDT. If none of the selected options work the
kernel tries to use one to get the serial console, then panics.

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
devices, not just those commonly used.
