SD/MMC Driver

Figure 15: Working Principle of SD/MMC

The SD/MMC card drivers under a Linux system typically include four parts
- SD/MMC core, mmc_block, mmc_queue and SD/MMC driver;



SD/MMC core implements the structure independent core code in

SD/MMC related operations;



mmc_block implements the driver structure used when SD/MMC

cards work as block devices;



mmc_queue implements management of the request queue;



SD/MMC driver implements the controller drivers;
