+* \brief Micron MT29F serial NAND driver
+*
+* This module allows read/write access to Micron MT29F serial
+* NANDs.
+* It is a block device, so it must be accessed using the KBlock
+* interface functions (see kblock.h).
+*
+* Once you have opened the flash for writing, you may want to use
+* kblock_trim() to avoid overwriting data on other flash banks.
+*
+* Example usage:
+* \code
+* Flash fls;
+* flash_init(&fls, 0);
+* // enable access only on desired blocks
+* // start block = 50, num blocks = 20
+* kblock_trim(&fls.blk, 50, 20);
+* // ...
+* // now write to the flash
+* // block number is automatically converted
+* kblock_write(&fls.blk, 0, buf, 0, 128);
+* \endcode
