The usual thing if it's straightforward to do so is to keep support for old versions even if the early revisions are not expected to be widely available. We do fairly often see problems with people still using old boards for various reasons - the fact that new silicon is available does not mean that the old silicon has been retired by users (even if just for comparison purposes while new board revisions are being brought up - "that worked on the rev A boards, did we break the software?") or that the old silicon isn't sitting in an assembly pipeline somewhere. --u3/rZRmxL6MmkK24 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAEBAgAGBQJS/i6lAAoJELSic+t+oim9H1AP/Rz+hidBjQgkbfxotQeOasQI OXMHdKUH/shuzHXrfPYnK5gCxFx2aGg6jeA7bVBqvitr+YbYquTt85JeLp3MOJB9 0cZSfRE3EMnZS0AD002tY+GOKsYLU1NAtcWF+KSR6f0ytBkN+h/9bJhF8OUiX4zF P0izCgX1PJKRdSlK66cU2rRhqs27A2hmdcDgEtvMstdfRz0wVRp2XyFtXXZpGy5G xU9f0llwbYKag7VoTOE+nsOFsUooQP3HbIprxYGIHbN9TNFCcWXaE+wFCYmj0UA4 di/nh2Aopk6Iz0RX7ldTS3KCi4i8clJAwoByZvf6rxuWpZNjVEhZKXfzlBhyqLg4 NhwjmnoQB1t0+ld2+wSv3R6IqGP4UFNtFQM405aUA1iiCCexqtXYI0n8PVcT5Ydu GGi32lzx6M3HwHsjpv0/eMzCb58FYM92AGat2l8WBDBemq/5v9URkjsYnRNX33cT JLU3nfI2PNuSB8VYqb4eprZHVwqajO9H1VrzsbYHQOANJWFfIJd4WNSJUVskAyRk g4mqMHyMazHQH272GSu9dJ6n/uW83awkJETEp0MA1YRfBdXDtySItnDahJg4KEo0 6+5g8RrKwDupVsdRRXi1cXRGzOsZ/rIxlXxk4OffaaJCvpaQEDWO0JOfqYcTyqCw sl5xTadq5JJ9txYVY2DI =+6kS -----END PGP SIGNATURE----- --u3/rZRmxL6MmkK24-- -- 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/
