<body>
<p>SDIO is an interface designed as an extension for the existing
SD card standard, to allow connecting different peripherals to
the host with the standard SD controller. Peripherals currently
sold at the general market include WLAN/BT modules, cameras,
fingerprint readers, barcode scanners. The 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 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. There is an
ongoing work to design a good locking model for the stack. WiFi
driver is able to load a firmware onto the card and initialize
it.</p>

<help>
<task>SDIO stack: Design a locking model, define how the
interrupts should be processed (on SDIO controller level, MMC
stack level and by child drivers).</task>
<task>Marvell SDIO WiFi: connect to the &os; network stack, write
the code to implement required functions (such as sending and
receiving data, network scanning, and so on).</task>
<task>Implement detach path. It cannot be tested on the DreamPlug
used for development, because it does not have an external
SDIO-capable slot.</task>
