prompt "CPU Caching mode"
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"
default y
help
This options indicates that JTAG will be used to debug the kernel. It
suppresses the use of certain hardware debugging features, such as
single-stepping, which are taken over completely by the JTAG unit.
config MN10300_RTC

This option enables support for the RTC, thus enabling time to be
tracked, even when system is powered down. This is available on-chip
on the MN103E010.

This options indicates that the watchdog timer will be used.
config PCI
bool "Use PCI"
depends on MN10300_UNIT_ASB2305
default y
help
Some systems (such as the ASB2305) have PCI onboard. If you have one
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
doesn't.
