config SH_UNKNOWN
bool "BareCPU"
help
"Bare CPU" aka "unknown" means an SH-based system which is not one
of the specific ones mentioned above, which means you need to enter
all sorts of stuff like CONFIG_MEMORY_START because the config
system doesn't already know what it is. You get a machine vector
without any platform-specific code in it, so things like the RTC may
not work.
This option is for the early stages of porting to a new machine.

config MEMORY_START
hex "Physical memory start address"
default "0x08000000"
---help---
Computers built with Hitachi SuperH processors always
map the ROM starting at address zero. But the processor
does not specify the range that RAM takes.
The physical memory (RAM) start address will be automatically
set to 08000000. Other platforms, such as the Solution Engine
boards typically map RAM at 0C000000.
Tweak this only when porting to a new machine which does not
already have a defconfig. Changing it from the known correct
value on any of the known systems will only lead to disaster.
config MEMORY_SIZE
hex "Physical memory size"
default "0x00400000"
help
This sets the default memory size assumed by your SH kernel. It can
be overridden as normal by the 'mem=' argument on the kernel command
line. If unsure, consult your board specifications or just leave it
as 0x00400000 which was the default value before this became
configurable.

Compact Flash is a small, removable mass storage device introduced
in 1994 originally as a PCMCIA device. If you say `Y' here, you
compile in support for Compact Flash devices directly connected to
a SuperH processor. A Compact Flash FAQ is available at
<http://www.compactflash.org/faqs/faq.htm>.
If your board has "Directly Connected" CompactFlash at area 5 or 6,
you may want to enable this option. Then, you can use CF as
primary IDE drive (only tested for SanDisk).
If in doubt, select 'N'.

Selecting this option will enable support for SH processors that

config KEXEC
bool "kexec system call (EXPERIMENTAL)"

help
kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot
but it is indepedent of the system firmware. And like a reboot
you can start any kernel with it, not just Linux.
The name comes from the similiarity to the exec system call.
It is an ongoing process to be certain the hardware in a machine
is properly shutdown, so do not be surprised if this code does not
initially work for you. It may help to enable device hotplugging
support. As of this writing the exact hardware interface is
strongly in flux, so no good recommendation can be made.
config PREEMPT
bool "Preemptible Kernel (EXPERIMENTAL)"

config SMP
bool "Symmetric multi-processing support"
---help---
This enables support for systems with more than one CPU. If you have
a system with only one CPU, like most personal computers, say N. If
you have a system with more than one CPU, say Y.
If you say N here, the kernel will run on single and multiprocessor
machines, but will use only one CPU of a multiprocessor machine. If
you say Y here, the kernel will run on many, but not all,
singleprocessor machines. On a singleprocessor machine, the kernel
will run faster if you say N here.
People using multiprocessor machines who say Y here should also say
Y to "Enhanced Real Time Clock Support", below.
See also the <file:Documentation/smp.txt>,
<file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available
at <http://www.tldp.org/docs.html#howto>.
If you don't know what to do here, say N.

help
This allows you to specify the maximum number of CPUs which this
kernel will support. The maximum supported value is 32 and the
minimum value which makes sense is 2.
This is purely to save memory - each supported CPU adds
approximately eight kilobytes to the kernel image.

help
Selecting this option will wakeup the User Break Controller (UBC) on
startup. Although the UBC is left in an awake state when the processor

power saving state, which causes issues with things like ptrace().

config ISA
bool

help
Find out whether you have ISA slots on your motherboard. ISA is the
name of a bus system, i.e. the way the CPU talks to the other stuff
inside your box. Other bus systems are PCI, EISA, MicroChannel
(MCA) or VESA. ISA is an older system, now being displaced by PCI;
newer boards don't support it. If you have ISA, say Y, otherwise N.
config EISA
bool
---help---
The Extended Industry Standard Architecture (EISA) bus was
developed as an open alternative to the IBM MicroChannel bus.
The EISA bus provided some of the features of the IBM MicroChannel
bus while maintaining backward compatibility with cards made for
the older ISA bus. The EISA bus saw limited use between 1988 and
1995 when it was made obsolete by the PCI bus.
Say Y here if you are building a kernel for an EISA-based machine.
Otherwise, say N.
