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

187 | number of data bits to protect, 'm' should be chosen such | |
