Why do you need the line above?
That is to avoid using a "#ifndef CONFIG_COLDFIRE" around these.
This entry clears out extra-y for the case when both CONFIG_MMU
and CONFIG_COLDFIRE are set.
Ooh, that's ugly, and easily overlooked (I missed it).
So you don't want head.o for Coldfire. What about
extra-$(CONFIG_MMU_MOTOROLA) := head.o
extra-$(CONFIG_SUN3) := sun3-head.o
But since head.o is not really about MMU or not, but about the machine,
perhaps it should be explicitly written as
extra-$(CONFIG_AMIGA) := head.o
extra-$(CONFIG_ATARI) := head.o
extra-$(CONFIG_SUN3X) := head.o
I am happy to do it either way. The second option here will need a
longer list. I count 8 machines that use head.o (assuming VME is a
single machine type) and 1 that uses sun3-head.o. At least the first
option above just has the 2 lines.
What is your preference?
The latter, as people are experimenting with MMU-less machines now.
