As a point of interest, none of those drivers should really depend on 
NIOS2.  They are usable on an ARM SoCFPGA system if the FPGA logic 
contains the corresponding Altera/Intel IP components.

Whether or not anyone needs them in barebox is another matter, but I 
have certainly used them in ARM SoCFPGA Linux systems booted from barebox.
