These are ALL functions that must be provided in your board-specific logic. Look for example a:
$ cd boards/arm/sama5/ $ grep -r sdio_mediachange * sama5d2-xult/src/sam_hsmci.c: sdio_mediachange(state->hsmci, cd); sama5d2-xult/src/sam_hsmci.c: sdio_mediachange(state->hsmci, state->cd); sama5d3x-ek/src/sam_hsmci.c: sdio_mediachange(state->hsmci, cd); sama5d3x-ek/src/sam_hsmci.c: sdio_mediachange(state->hsmci, state->cd); sama5d3-xplained/src/sam_hsmci.c: sdio_mediachange(state->hsmci, cd); sama5d3-xplained/src/sam_hsmci.c: sdio_mediachange(state->hsmci, state->cd); sama5d4-ek/src/sam_hsmci.c: sdio_mediachange(state->hsmci, cd); sama5d4-ek/src/sam_hsmci.c: sdio_mediachange(state->hsmci, state->cd);
