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.

+ +

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.

+ +

The only supported SD controller driver is + ti_sdhci, which is used on the BeagleBone Black. + Modifying other SDHCI-compliant drivers should not be + difficult.

+ + + + +

Rework bus/target/LUN enumeration and the locking model + — I don't really understand the CAM locking and am likely to + do it incorrectly.

+ + + +

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

+ + + +

Begin implementing SDIO-specific bits.
