No, not for the MMC on collie. At least, the patch to the 2.4 kernel which I based my 2.6 code on did not have any MMC parts, and the openzaurus distro at the time still included the binary module in the rom. IIRC, Chris Larson signed a NDA and got the specs for the MMC device on collie to develop it for 2.6, but I don't think anything ever came of it. I also might be remembering he signed a NDA for some other component, but I think it was the MMC device. Also, the poodle and collie used different device controllers, so the work will not transfer over. :( John - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
