	  Calculate checksum 8 bytes at a time with a clever slicing algorithm.
	  This is the fastest algorithm, but comes with a 8KiB lookup table.

	bool
	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 CONFIG_BCH_CONST_M
	  and CONFIG_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 CONFIG_BCH library supports
	  only a single (m,t) configuration. This is mainly useful
	  for NAND flash board drivers requiring known, fixed CONFIG_BCH
	  parameters.

config 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 CONFIG_BCH_CONST_PARAMS.

config 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

config CONFIG_GLOB
	bool
#	This actually supports modular compilation, but the module overhead

#	when required.  Since we're ignoring out-of-tree users,	there's also
#	no need bother prompting for a manual decision:
#	prompt "glob_match() function"
	help
	  This option provides a glob_match function for performing
	  simple text pattern matching.  It originated in the CONFIG_ATA code
	  to blacklist particular drive models, but other device drivers
	  may need similar functionality.

	  All drivers in the Linux kernel tree that require this function
	  should automatically select this option.  Say N unless you
	  are compiling an out-of tree driver which tells you that it
	  depends on this.

config CONFIG_GLOB_SELFTEST
	bool "glob self-test on init"
	default n
	depends on CONFIG_GLOB
	help
	  This option enables a simple self-test of the glob_match
	  function on startup.	It is primarily useful for people
	  working on the code to ensure they haven't introduced any
	  regressions.

	  It only adds a little bit of code and slows kernel boot (or
	  module load) by a small amount, so you're welcome to play with
	  it, but you probably don't need it.
