| The CN63XXP1 chip requires build time workarounds to |

| non-CN63XXP1 hardware, so it is recommended to select "n" |

| CVMSEG LM is a segment that accesses portions of the dcache as a |
| local memory; the larger CVMSEG is, the smaller the cache is. |
| This selects the size of CVMSEG LM, which is in cache blocks. The |
| legally range is from zero to 54 cache blocks (i.e. CVMSEG LM is |
| between zero and 6192 bytes). |
