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