Re-entrancy
This SWI is re-entrant.
Use
This SWI is used to claim a Device Vector of a SDIO card.
Notes
To simplify SDIO interrupt dispatch, device drivers should use this instead of calling OS_ClaimDeviceVector. Since SDIO cards are only supported on buses with one card per slot, there is no need to specify an RCA to identify the card.
