    Ah, right.

    Then, can't we use smp_prepare_cpus for this? it looks to be late enough
    so that we can use ioremap there.

    I don't want it to be an initcall. The code will be different on the
    A31, and we don't want it to be run on all the other machines whenever
    we boot a multiplatform kernel anyway.
