/****************************************************************************
 * Name:  sam_automount_event
 *
 * Description:
 *   The HSMCI card detection logic has detected an insertion or removal
 *   event.  It has already scheduled the MMC/SD block driver operations.
 *   Now we need to schedule the auto-mount event which will occur with a
 *   substantial delay to make sure that everything has settle down.
 *
 * Input Parameters:
 *   slotno - Identifies the HSMCI0 slot: HSMCI0 or HSMCI1_SLOTNO.
 *       There is a terminology problem here:  Each HSMCI supports two slots,
 *      slot A and slot B. Only slot A is used.  So this is not a really a
 *      slot, but an HSCMI peripheral number.
 *   inserted - True if the card is inserted in the slot.  False otherwise.
 *
 *  Returned Value:
 *    None
 *
 *  Assumptions:
 *    Interrupts are disabled.
