[PATCH] Add support for default env and mounting /boot to BeagleBoard

[Robert P. J. Day]

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?
