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

+config PREEMPT
+ bool "Preemptible Kernel"
+ help
+ This option reduces the latency of the kernel when reacting to
+ real-time or interactive events by allowing a low priority process to
+ be preempted even if it is in kernel mode executing a system call.
+ This allows applications to run more reliably even when the system is
+ under load.

+ Say Y here if you are building a kernel for a desktop, embedded
+ or real-time system. Say N if you are unsure.

+
+config MN10300_CURRENT_IN_E2
+ bool "Hold current task address in E2 register"
+ default y
+ help
+ This option removes the E2/R2 register from the set available to gcc
+ for normal use and instead uses it to store the address of the
+ current process's task_struct whilst in the kernel.
+
+ This means the kernel doesn't need to calculate the address each time
+ "current" is used (take SP, AND with mask and dereference pointer
+ just to get the address), and instead can just use E2+offset
+ addressing each time.
+
+ This has no effect on userspace.
+
+config MN10300_USING_JTAG
+ bool "Using JTAG to debug kernel"

+ single-stepping, which are taken over completely by the JTAG unit.

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