Re: Support for Arctic platform (405LP based)

[Cort Dougan <cort@fsmlabs.com>]

Would you be able to commit them to _2_4 instead so they're not in the
wildly divergent _2_4_devel tree?  That would definitely be handy when
trying to find where the working trees are.

} The patch below adds support for IBM's Arctic-II development system,
} based on the 405LP processor.  For now this is just the core support,
} more drivers coming soon.  Are there any objections, or suggestions
} for doing things better before I commit this to linuxppc_2_4_devel?
}
} In particular, I'd welcome comments on the handling of the bootstrap
} for Arctic:  the normal bootloader is PIBS, which is quite different
} from IBM OpenBIOS, but uses the same image format.  For now I'm *not*
} defining CONFIG_IBM_OPENBIOS, but duplicating the targets in the
} arch/ppc/boot/simple/Makefile so that we get a treeboot image.
