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

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

113 | the I/O region. | |

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