+    <code>CONFIG_PAGING_SDSLOT</code> identifies the slot number of the SD device to initialize.
+    This must be undefined if SD is not being used.
+    This should be defined to be zero for the typical device that has only a single slot (See <code>CONFIG_MMCSD_NSLOTS</code>).
+    If defined, <code>CONFIG_PAGING_SDSLOT</code> will instruct certain board-specific logic to initialize the media in this SD slot.
