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