With the submitted patches brcmsmac claims any revision of 802.11 cores.
Not sure what b43 claims. I have a patch internally to claim only
revisions 23 and 24, which are used in bcm43224, bcm43225, and bcm4313.

The problem is that ai_doattach() is returning NULL. I added pr_err() statements to each of the places that this could happen and found that the error in in this fragment:

        /* scan for cores */
        if (socitype == SOCI_AI) {
                SI_MSG("Found chip type AI (0x%08x)\n", w);
                /* pass chipc address instead of original core base */
                ai_scan(&sii->pub, pbus);
        } else {
                /* Found chip of unknown type */
                pr_err("Found chip of type %d\n", socitype);
                return NULL;
        }

This one logs "brcmsmac: Found chip of type 4". As SOC_AI is the only SOCI_XX that is defined, I am not sure that I will be able to get further.
