[U-Boot-Users] [PATCH] Fix 8xx build to conditionally compile fdt.o

[Jerry Van Baren <gvb.uboot@gmail.com>]

Change to COBJS-y method so that the fdt.o library can be properly
conditionally compiled.  Without this change, the mpc8xx boards that
don't use CONFIG_OF_LIBFDT still build the fdt.o, causing code bloat
and compile warnings.

Hi Wolfgang, 

Commit a6f5f317cd074bbbfa2aab4fca05904c811c19fb added fdt.o unconditionally.
    8xx : Add OF support to Adder875 board port - resubmit

I don't have any 8xx boards (especially no Adder boards) so I cannot
verify the patch doesn't break the boards, but it does compile cleanly
both with and w/o CONFIG_OF_LIBFDT.

Best regards,
gvb
