If you set MMC_SHIFT to 4, you'll get up to 16 partitions per card, but otoh you reduce the number of minor devices that this driver can handle. It's better to simply set MMC_NUM_MINORS to the number of minors you'd like (64?) instead of the 256 >> MMC_SHIFT. _______________________________________________ support mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/support
