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 | |
