128 default MN10300_CACHE_WBACK
129 help
130 This option determines the caching mode for the kernel.
131
132 Write-Back caching mode involves the all reads and writes causing
133 the affected cacheline to be read into the cache first before being
134 operated upon. Memory is not then updated by a write until the cache
135 is filled and a cacheline needs to be displaced from the cache to
136 make room. Only at that point is it written back.
137
138 Write-Through caching only fetches cachelines from memory on a
139 read. Writes always get written directly to memory. If the affected
140 cacheline is also in cache, it will be updated too.
141
142 The final option is to turn of caching entirely.

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

190config MN10300_CURRENT_IN_E2
191 bool "Hold current task address in E2 register"
192 default y
193 help
194 This option removes the E2/R2 register from the set available to gcc
195 for normal use and instead uses it to store the address of the
196 current process's task_struct whilst in the kernel.
197
198 This means the kernel doesn't need to calculate the address each time
199 "current" is used (take SP, AND with mask and dereference pointer
200 just to get the address), and instead can just use E2+offset
201 addressing each time.
202
203 This has no effect on userspace.

235 of these boards and you wish to use the PCI facilities, say Y here.
236
237 The PCI-HOWTO, available from
238 <http://www.tldp.org/docs.html#howto>, contains valuable
239 information about which PCI hardware does work under Linux and which
