You have two completely orthogonal problems: 1) changing b43 so it knows how to talk not just to SSB/PCI/PCMCIA chips but also SDIO chips 2) changing b43 so it knows how to talk to your specific radio/PHY chip, and LP PHY However, 1) is being solved for you by somebody on the IRC channel with whom Michael is in contact, and 2) is (hopefully) being solved for you by Larry and Gabor. Thus, the best thing you can do is familiarise yourself with the existing efforts and eventually try to put them together and test with your chip. johannes --=-nf7o4IE0DgcFRUN2rG6o Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJKkQhLAAoJEODzc/N7+Qma08AQAIexJywflkGxdDKBqjLiclbC AUGuUobW1csWDf77FdVKMmYLJ7iRTSO3hUGxbGislYVnm/g9b5md0RUiB0E46HE7 zw3VxqBYaqIAbHwxVN4GQ8Hi6eVTETq2g/MFhRsHvG+3utTTdsNI1O9YwPYdQhGL 3DrS8CF4APgP9ts6vJcv6N/G7S+uqeylt+3OqWTiXkfZiNf0Vm2HKJXUS4HSBTkn Oz5qat2MCQKDf5BJ0+XSyltcltmm4FunZWQQ7EKCde5gbOH6JPem007TBlBkxy+6 yMjrEpiRqYTvVYgYR0DSfbQ5ER/qVnQHiybknCLC3x/ziJUrnb9/zKxnZ/x3Zg7P gBDCf2B6UBYuzaVq4hbQ3PReu7upBVAUO8F8rmJ3eICuvDMD0GYmL/Bt47HkUAa7 jH9Fa/29WXiBY4uk49LHVWISB7pwT62Rqw0dyg1yL7lxtx4w92dyIjbzSZ8/nc3N AYnrJI2434LVOLwZLGqr3uonXSo94KGZ8yeBZgIwkWmk/ovxa8rlWBDNdWN2BNhW F+8TQmPNzNhgYGFftqbPJtlPTeL3e/XV7LRkJw8SoSQyLZD3q+fzRG8Apb9GBmD3 4izrYBp+9JhMow6jXmKWqr/jAhb9UUehaQTqB2lMb3ZWUfCOrt1paEi1rfPLpLC3 0FfiZ7fJ1wnt0481Kw7q =Bsl8 -----END PGP SIGNATURE----- --=-nf7o4IE0DgcFRUN2rG6o--
