  32         help
  33           This option adds an optional timeout parameter for DFU which, if set,
  34           will cause DFU to only wait for that many seconds before exiting.

  60           When flashing UBI images to NAND, enable the DROP_FFS flag to drop
  61           trailing all-0xff pages.

  85           This option enables using DFU to read and write to VIRTUAL device
  86           used at board level to manage specific behavior
  87           (OTP update for example).

  98         help
  99           DFU transfer uses a buffer before writing data to the
 100           raw storage device. This value can be used for setting the
 101           size of this buffer. The size of the buffer is also configurable
 102           through the "dfu_bufsiz" environment variable. If both are
 103           given the size of the buffer is set to "dfu_bufsize".

 108         help
 109           When updating files rather than the raw storage device,
 110           we use a static buffer to copy the file into and then write
 111           the buffer once we've been given the whole file.  Define
 112           this to the maximum filesize (in bytes) for the buffer.
 113           If undefined it defaults to the CONFIG_SYS_DFU_DATA_BUF_SIZE.
