126 prompt "CPU Caching mode"
127 default MN10300_CACHE_WBACK
129 This option determines the caching mode for the kernel.
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.
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.
141 The final option is to turn of caching entirely.

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

171 config KERNEL_ZIMAGE_BASE_ADDRESS
172 hex "Base address of compressed vmlinux image"
178 bool "Preemptible Kernel"
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
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.
189 config MN10300_CURRENT_IN_E2
190 bool "Hold current task address in E2 register"
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.
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.
202 This has no effect on userspace.
204 config MN10300_USING_JTAG
205 bool "Using JTAG to debug kernel"
208 This options indicates that JTAG will be used to debug the kernel. It
209 suppresses the use of certain hardware debugging features, such as
210 single-stepping, which are taken over completely by the JTAG unit.
213 bool "Using MN10300 RTC"
214 depends on MN10300_PROC_MN103E010
218 This option enables support for the RTC, thus enabling time to be
219 tracked, even when system is powered down. This is available on-chip

223 bool "Using MN10300 watchdog timer"
226 This options indicates that the watchdog timer will be used.
230 depends on MN10300_UNIT_ASB2305
233 Some systems (such as the ASB2305) have PCI onboard. If you have one
234 of these boards and you wish to use the PCI facilities, say Y here.
