| Some SH processors (such as SH-2/SH-2A) lack an MMU. In order to | |
| boot on these systems, this option must not be set. | |
| On other systems (such as the SH-3 and 4) where an MMU exists, | |

| Selecting this option will configure the caches to be direct-mapped, | |

| for debugging on platforms with 2 and 4-way caches (SH7750R/SH7751R, | |
| SH4-202, SH4-501, etc.) | |

| Selecting this option will configure the caches in write-through | |
