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.
</li>
<li>
<code>CONFIG_PAGING_M25PX</code>:
Use the m25px.c FLASH driver.
If this is selected, then the MTD interface to the MP25x device will be used to support paging.
</li>
<li>
<code>CONFIG_PAGING_M25PX_BINOFFSET</code>:
If CONFIG_PAGING_M25PX is defined then CONFIG_PAGING_M25PX_BINOFFSET will be used to specify the offset in bytes into the FLASH device where the NuttX binary image is located.
Default: 0
</li>
<li>
<code>CONFIG_PAGING_M25PX_SPIPORT</code>:
If CONFIG_PAGING_M25PX is defined and the device has multiple SPI busses (ports), then this configuration should be set to indicate which SPI port the M25Px device is connected.
Default: 0
</li>
