+    <body>
+      <p>The goal of this project is to reimplement the exisitng
+	MMC/SD stack using the CAM framework.  This will permit utilizing
+	the well-tested CAM locking model and debug features.
+	Additionally, it will be possible to process interrupts generated
+	by the inserted card, which is a prerequisite for implementing the
+	SDIO interface.</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/from the card.</p>
+
+      <p>The only supported SD controller driver is
+	<tt>ti_sdhci</tt>, which is used on the BeagleBone Black.
+	Modifying other SDHCI-compliant drivers should not be
+	difficult.</p>
