+ <body>
+ <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 debugging
+ 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 the WiFi/BT modules found on many
+ development boards, like Raspberry Pi 3.</p>
+
+ <p>Another feature that the new stack will have is support for
+ sending SD commands from userland applications using
+ <tt>cam(3)</tt>. This will allow for building device drivers in
+ userland and make debugging much easier.</p>
+
+ <p>The new stack is able to attach to the SD card and bring it
+ to an operational state so that it is possible to read and
+ write to the card.</p>
+
+ <p>The stack has been tested to work on the Beaglebone Black and
+ Wandboard Quad platforms.</p>
+
+ <p>Currently the code is being prepared for inclusion in the
+ &os; source tree. <tt>cam(3)</tt> is being extended to
+ support SDIO-specific functions (reading registers, managing
+ interrupts).</p>
