[U-Boot-Users] ppc start.S 'rfmci' opcode not recognized by ppc-440 compiler

[k b]

Hi,
I'm working on a amcc taishan board.
The board works find with for u-boot 1.1.3 and 1.1.6. 
I'm using montavista ppc_440-gcc  build tools.
But any version after 1.2.0  compilation fails at start.S
apparently it complains about an Unrecognized opcode 'rfmci (message show below)

Questions:

1) also i made a change in the Makefile show above which made me wonder if using ppc_8xx as the default for all ppc board is a correct assumption ? 
maybe its just a place holder. or maybe the rfmci is only available in ppc_8xx. 
2) other question is what option do i have to use the latest u-boot 1.3.1 with my ppc_440 build tools as it doesn't recognizes 'rfmci' opcode.


any insights would be appreciated.
Thanks in advance !

-----------------------------------
change that i made in Makefile
-----------------------------------
 
ifeq ($(ARCH),ppc)
CROSS_COMPILE = ppc_8xx-
endif
to 
ifeq ($(ARCH),ppc)
CROSS_COMPILE = ppc_440-
endif
