    description   "

        In theory it is possible to read back the entire flash contents using

        a single SPI transaction.  However, some SPI bus drivers have a maximum

        transaction size - for example transactions may be limited to the

        length of a DMA bounce buffer.  Setting this option to a non-zero value

        specifies the maximum SPI bus transfer size which will be used when

        reading back data.  Read requests for areas larger than this block size

        will automatically be split into a series of smaller SPI bus transactions.
