86 | help | |
87 | If you wish to use more than 256MB of memory with your MMU based | |
88 | system, you will need to select this option. The kernel can only see | |
89 | the memory between 0xC0000000 and 0xD0000000 directly... everything | |
90 | else must be kmapped. | |

110 | This option sets the base address for the uClinux kernel. The kernel | |

114 | the I/O region. | |

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

291 | This option controls what data, if any, should be placed in the GP | |
