[U-Boot] File name substitution in linker scripts

[Stefan Roese]

I'm wondering if and how it's possible to use a "variable" file name for 
inclusion in a linker script. Reason for this is the consolidation of the 
ppc4xx linker scripts, where some boards (PPC440) include a board specific 
file (e.g. board/amcc/canyonlands/init.o) into the section "bootpg":

  .bootpg RESET_VECTOR_ADDRESS - 0xffc :
  {
    cpu/ppc4xx/start.o	(.bootpg)
    board/amcc/canyonlands/init.o	(.bootpg)
  }

Is there a way to write something like this:

  .bootpg RESET_VECTOR_ADDRESS - 0xffc :
  {
    cpu/ppc4xx/start.o	(.bootpg)
    board/$(BOARDDIR)/init.o	(.bootpg)
  }

in a linker script?

Thanks.

Cheers,
Stefan
