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> + </body> + + <help> + <task> + <p>Modify the SDHCI driver on at least one x86 platform.
