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