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

167 config INTERRUPT_VECTOR_BASE
168 hex "Base address of vector table"
171 The base address of the vector table will be programmed into
172 the TBR register. It must be on 16MiB address boundary.

178 config KERNEL_ZIMAGE_BASE_ADDRESS
179 hex "Base address of compressed vmlinux image"
185 bool "Preemptible Kernel"
187 This option reduces the latency of the kernel when reacting to
188 real-time or interactive events by allowing a low priority process to
189 be preempted even if it is in kernel mode executing a system call.
190 This allows applications to run more reliably even when the system is
193 Say Y here if you are building a kernel for a desktop, embedded
194 or real-time system. Say N if you are unsure.
196 config MN10300_CURRENT_IN_E2
197 bool "Hold current task address in E2 register"
200 This option removes the E2/R2 register from the set available to gcc
201 for normal use and instead uses it to store the address of the
202 current process's task_struct whilst in the kernel.
204 This means the kernel doesn't need to calculate the address each time
205 "current" is used (take SP, AND with mask and dereference pointer
206 just to get the address), and instead can just use E2+offset
207 addressing each time.
209 This has no effect on userspace.
211 config MN10300_USING_JTAG
212 bool "Using JTAG to debug kernel"
215 This options indicates that JTAG will be used to debug the kernel. It
216 suppresses the use of certain hardware debugging features, such as
217 single-stepping, which are taken over completely by the JTAG unit.
220 bool "Using MN10300 RTC"
221 depends on MN10300_PROC_MN103E010
225 This option enables support for the RTC, thus enabling time to be
226 tracked, even when system is powered down. This is available on-chip

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