Questions answered in S3C2410A%20SDMMC卡块驱动使用手册 manuals
How do I create a block device node for the driver?
Use the mknod command, for example: `mknod /dev/zlg_fsa b 200 1` to create the first block device node.
What is the correct order to load the SD/MMC driver modules?
First load `zlg_f.ko`, then load `mmc2410.ko`. To unload, reverse the order.
