127 prompt "CPU Caching mode"
128 default MN10300_CACHE_WBACK
130 This option determines the caching mode for the kernel.
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.
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.
142 The final option is to turn of caching entirely.

161 config INTERRUPT_VECTOR_BASE
162 hex "Base address of vector table"
165 The base address of the vector table will be programmed into
166 the TBR register. It must be on 16MiB address boundary.

172 config KERNEL_ZIMAGE_BASE_ADDRESS
173 hex "Base address of compressed vmlinux image"
179 bool "Preemptible Kernel"
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
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.
190 config MN10300_CURRENT_IN_E2
191 bool "Hold current task address in E2 register"
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.
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.
203 This has no effect on userspace.
205 config MN10300_USING_JTAG
206 bool "Using JTAG to debug kernel"
209 This options indicates that JTAG will be used to debug the kernel. It
210 suppresses the use of certain hardware debugging features, such as
211 single-stepping, which are taken over completely by the JTAG unit.
214 bool "Using MN10300 RTC"
215 depends on MN10300_PROC_MN103E010
219 This option enables support for the RTC, thus enabling time to be
220 tracked, even when system is powered down. This is available on-chip
223 config MN10300_WD_TIMER
224 bool "Using MN10300 watchdog timer"
227 This options indicates that the watchdog timer will be used.
231 depends on MN10300_UNIT_ASB2305
234 Some systems (such as the ASB2305) have PCI onboard. If you have one
235 of these boards and you wish to use the PCI facilities, say Y here.
