General
The SD Host controller is just a standard SD host controller. You can get a simplified specification which is detailed enough to implement everything you need to access SD cards from the SD Association - see "Part A2 - SD Host Controller Simplified Specification". Both the BSD (e.g. OpenBSD) and the Linux kernel come with an implementation.
