  config CRC32_SLICEBY8
  	bool "Slice by 8 bytes"
  	help
  	  Calculate checksum 8 bytes at a time with a clever slicing algorithm.
  	  This is the fastest algorithm, but comes with a 8KiB lookup table.
  	  Most modern processors have enough cache to hold this table without
  	  thrashing the cache.
  
  	  This is the default implementation choice.  Choose this one unless
  	  you have a good reason not to.
  
  config CRC32_SLICEBY4

  	boolean
  	help
  	  Drivers may select this option to force specific constant
  	  values for parameters 'm' (Galois field order) and 't'
  	  (error correction capability). Those specific values must
  	  be set by declaring default values for symbols BCH_CONST_M
  	  and BCH_CONST_T.
  	  Doing so will enable extra compiler optimizations,
  	  improving encoding and decoding performance up to 2x for
  	  usual (m,t) values (typically such that m*t < 200).
  	  When this option is selected, the BCH library supports
  	  only a single (m,t) configuration. This is mainly useful
  	  for NAND flash board drivers requiring known, fixed BCH
  	  parameters.
  
  config BCH_CONST_M

  	  Constant value for Galois field order 'm'. If 'k' is the
  	  number of data bits to protect, 'm' should be chosen such
  	  that (k + m*t) <= 2**m - 1.
  	  Drivers should declare a default value for this symbol if
  	  they select option BCH_CONST_PARAMS.
