84 | If you wish to use more than 256MB of memory with your MMU based | |

86 | the memory between 0xC0000000 and 0xD0000000 directly... everything | |

111 | the I/O region. | |

155 | prompt "CPU Caching mode" | |
156 | default FRV_DEFL_CACHE_WBACK | |
157 | help | |
158 | This option determines the default caching mode for the kernel. | |
159 | ||
160 | Write-Back caching mode involves the all reads and writes causing | |
161 | the affected cacheline to be read into the cache first before being | |
162 | operated upon. Memory is not then updated by a write until the cache | |
163 | is filled and a cacheline needs to be displaced from the cache to | |
164 | make room. Only at that point is it written back. | |
165 | ||
166 | Write-Behind caching is similar to Write-Back caching, except that a | |
167 | write won't fetch a cacheline into the cache if there isn't already | |
168 | one there; it will write directly to memory instead. | |
169 | ||
170 | Write-Through caching only fetches cachelines from memory on a | |
171 | read. Writes always get written directly to memory. If the affected | |
172 | cacheline is also in cache, it will be updated too. | |
173 | ||
174 | The final option is to turn of caching entirely. | |
175 | ||
176 | Note that not all CPUs support Write-Behind caching. If the CPU on | |
177 | which the kernel is running doesn't, it'll fall back to Write-Back | |
178 | caching. | |
