127 default MN10300_CACHE_WBACK
128 help
129 This option determines the caching mode for the kernel.
130
131 Write-Back caching mode involves the all reads and writes causing
132 the affected cacheline to be read into the cache first before being
133 operated upon. 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.

177config PREEMPT
178 bool "Preemptible Kernel"
179 help
180 This option reduces the latency of the kernel when reacting to
181 real-time or interactive events by allowing a low priority process to
182 be preempted even if it is in kernel mode executing a system call.
183 This allows applications to run more reliably even when the system is
184 under load.
185
186 Say Y here if you are building a kernel for a desktop, embedded
187 or real-time system. Say N if you are unsure.

190 bool "Hold current task address in E2 register"
191 default y
192 help
193 This option removes the E2/R2 register from the set available to gcc
194 for normal use and instead uses it to store the address of the
195 current process's task_struct whilst in the kernel.
196
197 This means the kernel doesn't need to calculate the address each time
198 "current" is used (take SP, AND with mask and dereference pointer
199 just to get the address), and instead can just use E2+offset
200 addressing each time.

234 of these boards and you wish to use the PCI facilities, say Y here.
