+      <p>SDIO is an interface designed as an extension of 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, 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.  The XPT layer is almost
+	ready, what is missing is a SIM module, for which a modified
+	version of SDHCI controller driver will be used, and a
+	peripheral module, where porting the <tt>mmcsd(4)</tt> driver is
+	required.</task>
+      <task>Marvell SDIO WiFi: connect it to the &os; network stack,
+	write the code to implement required functions, such as sending
+	and receiving data, network scanning and so on.</task>
