Heh. You tell me my first approach: http://ozlabs.org/pipermail/linuxppc-dev/2008-May/056730.html (mmc_spi) The OF people didn't like the patch which was used to support this approach: http://ozlabs.org/pipermail/linuxppc-dev/2008-May/056728.html The board info has another problem though. We can't remove it, thus we can't implement module_exit() for the 'OF glue'. -- Anton Vorontsov email: [EMAIL PROTECTED] irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
