+/* This logic supports some special options that can be used to create an
+ * MTD device on the SPIFI FLASH.
+ *
+ *    CONFIG_LPC43_SPIFI - Enable SPIFI support
+ *
+ * SPIFI device geometry:
+ *
+ *   CONFIG_SPIFI_OFFSET - Offset the beginning of the block driver this many
+ *     bytes into the device address space.  This offset must be an exact
+ *     multiple of the erase block size (CONFIG_SPIFI_BLKSIZE). Default 0.
+ *   CONFIG_SPIFI_BLKSIZE - The size of one device erase block.  If not defined
+ *     then the driver will try to determine the correct erase block size by
+ *     examining that data returned from spifi_initialize (which sometimes
+ *     seems bad).
+ *
+ * Other SPIFI options
+ *
+ *   CONFIG_SPIFI_LIBRARY - Don't use the LPC43xx ROM routines but, instead,
+ *     use an external library implementation of the SPIFI interface.
+ *   CONFIG_SPIFI_SECTOR512 - If defined, then the driver will report a more
+ *     FAT friendly 512 byte sector size and will manage the read-modify-write
+ *     operations on the larger erase block.
+ *   CONFIG_SPIFI_READONLY - Define to support only read-only operations.

+ * Description:

+ *   devices are not registered in the file system, but are created as
+ *   instances that can be bound to other functions (such as a block or
+ *   character driver front end).
+ *
+ *   SPIFI interface clocking is configured per settings in the board.h file.
+ *
+ * Input Parameters:
+ *   None
+ *
+ * Returned value:
+ *   One success, a reference to the initialized MTD device instance is
+ *   returned;  NULL is returned on any failure.
