Subject: [PATCH] Add support for default env and mounting /boot to BeagleBoard
To: "U-Boot Version 2 (barebox)" <barebox@lists.infradead.org>
Stealing shamelessly from the panda/board.c file, add equivalent
support for checking for the default environment and automounting the
/boot partition on the SD card.
Also, include the necessary header files for this, and fix the
filename reference at the top of the file.

a quick and dirty theft of code from panda/board.c, it builds and
boots and appears to work. thoughts?
