A little bit -- sort of.  I've seen chunks of code that have been
copied from Linux to U-Boot, and chunks of code in Linux and U-Boot
that appear to have come from the same place at some silicon vendor or
other.  And there are bits of code I've written that ended up in both
places.

But Linux and U-Boot don't share actual files, and any changes to the
"common" code has to be done twice.
