Right after playing your spi_mmc.c, I started this one based on generic mmc framework last night. I tried hard to recall my memory about mmc/sd, and hoped to catch up the merge window. Do you mean "parity" as crc? Crc is not supported, but can be added. I make some command set translation when spi doesn't support. > it's too bad the new framework doesnt allow for dynamic probing like the spi > layer. makes it a pain to work with a SPI/MMC card that can have the CS > changed on the fly. > -mike > Maybe we can move spi_setup_slave to the mmc->init() and do probing. Or shall we add a subcommand? Cheers, Thomas _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
