128 config MN10300_HAS_ATOMIC_OPS_UNIT

132 capable of doing LL/SC equivalent operations.

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

178 The base address of the vector table will be programmed into

185 config KERNEL_ZIMAGE_BASE_ADDRESS
186 hex "Base address of compressed vmlinux image"
192 bool "Preemptible Kernel"
194 This option reduces the latency of the kernel when reacting to
195 real-time or interactive events by allowing a low priority process to
196 be preempted even if it is in kernel mode executing a system call.
197 This allows applications to run more reliably even when the system is
200 Say Y here if you are building a kernel for a desktop, embedded
201 or real-time system. Say N if you are unsure.
203 config MN10300_CURRENT_IN_E2
204 bool "Hold current task address in E2 register"
207 This option removes the E2/R2 register from the set available to gcc
208 for normal use and instead uses it to store the address of the
209 current process's task_struct whilst in the kernel.
211 This means the kernel doesn't need to calculate the address each time
212 "current" is used (take SP, AND with mask and dereference pointer
213 just to get the address), and instead can just use E2+offset
214 addressing each time.
216 This has no effect on userspace.
218 config MN10300_USING_JTAG
219 bool "Using JTAG to debug kernel"
222 This options indicates that JTAG will be used to debug the kernel. It
223 suppresses the use of certain hardware debugging features, such as
224 single-stepping, which are taken over completely by the JTAG unit.
227 bool "Using MN10300 RTC"
228 depends on MN10300_PROC_MN103E010
232 This option enables support for the RTC, thus enabling time to be
233 tracked, even when system is powered down. This is available on-chip
236 config MN10300_WD_TIMER
237 bool "Using MN10300 watchdog timer"
240 This options indicates that the watchdog timer will be used.
244 depends on MN10300_UNIT_ASB2305
247 Some systems (such as the ASB2305) have PCI onboard. If you have one
248 of these boards and you wish to use the PCI facilities, say Y here.
250 The PCI-HOWTO, available from
251 <http://www.tldp.org/docs.html#howto>, contains valuable
252 information about which PCI hardware does work under Linux and which
