# Builds the boot partition for a chumby Falconwing-based platform.
# Note that bootstream-chumby.bin is a binary-blob combination of
# chumby_stub, and the Freescale-provided bootlets that set up power,
# clocks, and RAM. It is provided as a blob because Freescale provides
# elftosb2 as a blob. If you would like to recreate these from scratch and
# are on an x86 Linux machine, you'll need the following files:
# http://files.chumby.com/source/falconwing/bootloader/elftosb2;name=elftosb2
# http://files.chumby.com/source/falconwing/bootloader/falconwing_chumby_sb.db;name=chumbyconfig
