Thu Aug 19 19:15:54 UTC 2010
The checksums of the archive changed, which means the recipe needed to be updated to match.

+# 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:
