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

194      number of data bits to protect, 'm' should be chosen such
195      that (k + m*t) <= 2**m - 1.
196      Drivers should declare a default value for this symbol if
197      they select option BCH_CONST_PARAMS.
198
