config BCH_CONST_PARAMS
	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
	int
	range 5 15
	help
	  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.

config BCH_CONST_T
	int
	help
	  Constant value for error correction capability in bits 't'.
	  Drivers should declare a default value for this symbol if
	  they select option BCH_CONST_PARAMS.

	  If unsure, say N.
