You have the source code of the switch driver software? And it comes
with a GPL compatible license?

I would conside the switch driver code to be  driver  code  like  any
othr,  i.  e.  it  should  go into the drivers/ directory and then be
linked with U-Boot like any other U-Boot code.

Don't play any tricks with modifying the linker command line. Just add
your driver code like any other driver to the source tree and let the
exsiting Makefiles do the rest.

The day-to-day travails of the IBM programmer are so amusing to  most
of us who are fortunate enough never to have been one - like watching
Charlie Chaplin trying to cook a shoe.
