Peripherals currently + sold at the general market include WLAN/BT modules, cameras, + fingerprint readers, and barcode scanners. The &os; driver is + implemented as an extension to the existing MMC bus, adding a + lot of new SDIO-specific bus methods. A prototype of the driver + for the Marvell SDIO WLAN/BT (Avastar 88W8787) module is also + being developed, using the existing Linux driver as the + reference.</p> + + <p>SDIO card detection and initialization already work, most + needed bus methods are implemented and tested.</p> + + <p>WiFi driver is able to load a firmware onto the card and + initialize it. Migration of the MMC stack to the new locking + model is necessary in order to work with SDIO cards effectively. + The &os; CAM implementation is believed to be a good choice. + There is an ongoing work to implement an MMC transport for + CAM.</p> + </body> + + <help> + <task>SDIO stack: finish CAM migration.
