Nope, that's not the right way of doing things. First and foremost, a
missing hash in the hash file is currently not a hard failure, only a
warning. It will be turned into a hard failure soon, but with
appropriate handling of custom versions (see the patch series being
sent by Yann E. Morin and Arnout Vandecappelle about this).

The problem with your patch is that it adds just the hash file 2013.10.
What about the dozens of other U-Boot releases? And the zillions of
U-Boot forks all over the place?

Since it doesn't scale, we're going t keep it is simple: a hash for the
default U-Boot version currently used by Buildroot, and that's it.

Best regards,

Thomas
