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

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