In practice those binary.0 files are not really part of the Barebox
source code. The binary.0 file has to be extracted from a vendor U-Boot
binary prior to doing the Barebox build, so it isn't exactly part of
the "source tree".

Though I agree it is probably easier to extract them once and keep them
around in the source tree (not checked-in, of course).

Note that U-Boot now has a fully open-source implementation of this
binary.0 thing, at least for Armada XP and Armada 38x. However, it's
basically copy/pasted from the vendor U-Boot, so it's not very pretty
to look at:

 - http://git.denx.de/?p=u-boot.git;a=tree;f=drivers/ddr/marvell
   for the DDR initialization code.

 - http://git.denx.de/?p=u-boot.git;a=tree;f=arch/arm/mach-mvebu/serdes
   for the SERDES lane initialization

Best regards,

Thomas
