Description
This unit implements the standards based part of the SD/MMC specification including the standard SDHCI interfaces.
For each platform a SDHCI module needs to be provided that implements the platform specific parts of the SDHCI interface.
This is similar in model to USB and other interfaces in Ultibo, where the generic interface unit requires a platform specific module to register with it in order to communicate with platform specific devices.
The SD/MMC interfaces are 2 tier (ie Host and Device) whereas the USB interface is 3 tier (Host, Device and Driver).
