-* 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
