Memory is not then updated by a write until the cache 134 is filled and a cacheline needs to be displaced from the cache to 135 make room. Only at that point is it written back. 136 137 Write-Through caching only fetches cachelines from memory on a 138 read. Writes always get written directly to memory. If the affected 139 cacheline is also in cache, it will be updated too. 140 141 The final option is to turn of caching entirely. 142 143config MN10300_CACHE_WBACK 144 bool "Write-Back" 145 146config MN10300_CACHE_WTHRU 147 bool "Write-Through" 148 149config MN10300_CACHE_DISABLED 150 bool "Disabled" 151 152endchoice 153 154menu "Memory layout options" 155 156config KERNEL_RAM_BASE_ADDRESS 157 hex "Base address of kernel RAM" 158 default "0x90000000" 159 160config INTERRUPT_VECTOR_BASE 161 hex "Base address of vector table" 162 default "0x90000000" 163 help 164 The base address of the vector table will be programmed into 165 the TBR register.
