+      <p>The goal of this project is to reimplement the existing
+	MMC/SD stack using the CAM framework. This will permit
+	utilizing the well-tested CAM locking model and debug
+	features. It will also be possible to process interrupts
+	generated by the inserted card, which is a prerequisite for
+	implementing the SDIO interface. SDIO support is necessary for
+	communicating with WiFi/BT modules found on many development
+	boards, like Wan Raspberry Pi 3.</p>
+
+      <p>Another feature that the new stack will have is support for
+	sending SD commands from the userland applications using
+	<tt>cam(3)</tt>.  This will allow to build device drivers in
+	userland and make debugging much easier.</p>
+
+      <p>The first version of the code was uploaded to Phabricator for
+	review. The new stack is able to attach to the SD card and
+	bring it to an operational state so it is possible to read and
+	write to the card.</p>
+
+      <p>Support for the imx_sdhci SD Host Controller (used on
+	iMX-based boards, for example Wandboard) was added in 2016Q1,
+	along with ti_sdhci, which is used on the BeagleBone Black.
+	Modifying other SDHCI-compliant drivers should not be
+	difficult.</p>
