The SD/MMC interfaces are normally 2 tier (ie Host and Device) whereas the USB interface is 3 tier (Host, Device and Driver) however SDIO support adds a driver model to encapsulate support for device functions which can provide a variety of functionality including WiFi, Bluetooth, Ethernet and others.

MMC response type MMC_RSP_*

From: /include/linux/mmc/mmc.h

Native
`MMC_RSP_PRESENT = (1 shl 0);`
`MMC_RSP_136 = (1 shl 1);`	136 bit response
`MMC_RSP_CRC = (1 shl 2);`	Expect valid crc
`MMC_RSP_BUSY = (1 shl 3);`	Card may send busy
`MMC_RSP_OPCODE = (1 shl 4);`	Response contains opcode

These are the native response types, and correspond to valid bit patterns of the above flags. One additional valid pattern is all zeros, which means we don't expect a response.
`MMC_RSP_NONE = (0);`
`MMC_RSP_R1 = (MMC_RSP_PRESENT or MMC_RSP_CRC or MMC_RSP_OPCODE);`
`MMC_RSP_R1B = (MMC_RSP_PRESENT or MMC_RSP_CRC or MMC_RSP_OPCODE or MMC_RSP_BUSY);`

`MMC_CMD_BC = (2 shl 5);`	Broadcast Command, no Response
`MMC_CMD_BCR = (3 shl 5);`	Broadcast Command with Response

MMC SPI response type MMC_RSP_SPI_*

`MMC_RSP_SPI_S1 = (1 shl 7);`	One status byte
`MMC_RSP_SPI_S2 = (1 shl 8);`	Second byte
`MMC_RSP_SPI_B4 = (1 shl 9);`	Four data bytes
`MMC_RSP_SPI_BUSY = (1 shl 10);`	Card may send busy

+'''Ultibo MMC/SD/SDIO Interface unit'''
 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.
+A fully standards compliant SDHCI host controller needs only a procedure to register it with the SD/MMC core and it can operate using the standard functions provided in this unit, any deviations from the standard will require custom functions to be provided to override the standard functionality.
 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).
+The SD/MMC interfaces are normally 2 tier (ie Host and Device) whereas the USB interface is 3 tier (Host, Device and Driver) however SDIO support adds a driver model to encapsulate support for device functions which can provide a variety of functionality including WiFi, Bluetooth, Ethernet and others.
