Jimmy, who from NVIDIA should be on this review?  I assume that the work to add
boot device parameters to the config file will be effected by my changes to
cbootimage and I want to make sure the correct people from NVIDIA are in the
loop.

Thanks,
    Anton

Peer, Jimmy asked me to add you to this CL.  I have written a simple tool to
print out the contents of a BCT in human readable form.  It shares a lot of
cbootimage code.  This refactor splits out some code that I wanted to use in it.
 Once this CL is in I can send you the next one that actually adds the tool to
the makefile and adds the top level C file.

Thanks,
    Anton
