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.

+ +

Another feature that the new stack will have is support for + sending SD commands from the userland applications using + cam(3). This will allow to build device drivers in + userland and make debugging much easier.

+ +

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.

+ +

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.

+ + + + +

Modify the SDHCI driver on at least one x86 platform. This + will make development and collaboration easier.

+ + + +

Begin implementing SDIO-specific bits.
