+ 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.
