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 ! kunal
