Unrecognized opcode: `mtdcr'

Hi,

I just started trying to play with my new Ebony board...

I noticed now 'as' complains: Unrecognized opcode: `mtdcr'
when I do this:
	make ebony_config
	make mrproper
	make menuconfig
	make dep
	make zImage

But, if I do this:
	make walnut_config
	make mrproper
	make menuconfig
	make dpe
	make zImage

I can make a zImage just fine.

Of course I can manually add '-Wa,-m405' into my CFLAGS in
the Makefile, and it will build ok, but I'm thinking that's
not what I want to do.

My 'as' says:

[scameron@zuul sslinux]$ /usr/local/powerpc-linux/bin/as --version
GNU assembler 2.12

I also tried binutils 2.12.1, with the same results.

Any ideas?

Thanks,

I think we need to change arch/ppc/Makefile from:
ifdef CONFIG_40x
CFLAGS := $(CFLAGS) -Wa,-m405
endif

To:
ifdef CONFIG_4xx
CFLAGS := $(CFLAGS) -Wa,-m405
endif

For the moment.  Until there's some 440-specific opcodes we use (are
there any?) which means we'll need to do -Wa,-m440.

Matt, do you want to do this or shall I?
