	bool

	default y

	help

	  Xtensa processors are 32-bit RISC machines designed by Tensilica

	  primarily for embedded systems.  These processors are both

	  configurable and extensible.  The Linux port to the Xtensa

	  architecture supports all processor configurations and extensions,

	  with reasonable minimum requirements.  The Xtensa Linux project has

	  a home page at <http://xtensa.sourceforge.net/>.

config XTENSA_CPU_LINUX_BE

	bool "linux_be"

	---help---

	  The linux_be processor configuration is the baseline Xtensa

	  configurations included in this kernel and also used by

	  binutils, gcc, and gdb. It contains no TIE, no coprocessors,

	  and the following configuration options:



	  Code Density Option                2 Misc Special Registers

	  NSA/NSAU Instructions              128-bit Data Bus Width

	  Processor ID                       8K, 2-way I and D Caches

	  Zero-Overhead Loops                2 Inst Address Break Registers

	  Big Endian                         2 Data Address Break Registers

	  64 General-Purpose Registers       JTAG Interface and Trace Port

	  17 Interrupts                      MMU w/ TLBs and Autorefill

	  3 Interrupt Levels                 8 Autorefill Ways (I/D TLBs)

	  3 Timers                           Unaligned Exceptions

endchoice



config MMU

	bool

	default y



config XTENSA_UNALIGNED_USER

	bool "Unaligned memory access in use space"

	---help---

	   The Xtensa architecture currently does not handle unaligned

	   memory accesses in hardware but through an exception handler.

	   Per default, unaligned memory accesses are disabled in user space.



	   Say Y here to enable unaligned memory access in user space.



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.

           Unfortunately the kernel code has some race conditions if both

           CONFIG_SMP and CONFIG_PREEMPT are enabled, so this option is

           currently disabled if you are building an SMP kernel.



           Say Y here if you are building a kernel for a desktop, embedded

           or real-time system.  Say N if you are unsure.



config MATH_EMULATION

	bool "Math emulation"

	help

	Can we use information of configuration file?



config HIGHMEM

menu "Platform options"



choice

config XTENSA_PLATFORM_ISS

	bool "ISS"

	help

	  ISS is an acronym for Tensilica's Instruction Set Simulator.



config XTENSA_PLATFORM_XT2000

	bool "XT2000"

	help

	  XT2000 is the name of Tensilica's feature-rich emulation platform.

	  This hardware is capable of running a full Linux distribution.



endchoice





config XTENSA_CALIBRATE_CCOUNT

	bool "Auto calibration of the CPU clock rate"

	---help---

	  On some platforms (XT2000, for example), the CPU clock rate can

	  vary.  The frequency can be determined, however, by measuring

	  against a well known, fixed frequency, such as an UART oscillator.



config XTENSA_CPU_CLOCK

	int "CPU clock rate [MHz]"

	depends on !XTENSA_CALIBRATE_CCOUNT

	default "16"



config GENERIC_CALIBRATE_DELAY

	bool "Auto calibration of the BogoMIPS value"

	---help---

	  The BogoMIPS value can easily derived from the CPU frequency.



config CMDLINE_BOOL

	bool "Default bootloader kernel arguments"



config CMDLINE

	string "Initial kernel command string"

	depends on CMDLINE_BOOL

	default "console=ttyS0,38400 root=/dev/ram"

	help

	  On some architectures (EBSA110 and CATS), there is currently no way

	  for the boot loader to pass arguments to the kernel. For these

	  architectures, you should supply some command-line options at build

	  time by entering them here. As a minimum, you should specify the

	  memory size and the root device (e.g., mem=64M root=/dev/nfs).



config SERIAL_CONSOLE

	bool

	depends on XTENSA_PLATFORM_ISS

	default y

config PCI

	bool "PCI support" if !XTENSA_PLATFORM_ISS

	depends on !XTENSA_PLATFORM_ISS

	default y

	help

	  Find out whether you have a PCI motherboard. PCI 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 ISA, EISA, MicroChannel (MCA) or

	  VESA. If you have PCI, say Y, otherwise N.



	  The PCI-HOWTO, available from

	  <http://www.linuxdoc.org/docs.html#howto>, contains valuable

	  information about which PCI hardware does work under Linux and which

	  doesn't



source "drivers/pci/Kconfig"



config HOTPLUG



	bool "Support for hot-pluggable devices"

	---help---

	Say Y here if you want to plug devices into your computer while

	the system is running, and be able to use them quickly.  In many

	cases, the devices can likewise be unplugged at any time too.



	One well known example of this is PCMCIA- or PC-cards, credit-card

	size devices such as network cards, modems or hard drives which are

	plugged into slots found on all modern laptop computers.  Another

	example, used on modern desktops as well as laptops, is USB.



	Enable HOTPLUG and KMOD, and build a modular kernel.  Get agent

	software (at <http://linux-hotplug.sourceforge.net/>) and install it.

	Then your kernel will automatically call out to a user mode "policy

	agent" (/sbin/hotplug) to load modules and set up software needed

	to use devices as you hotplug them.

# only elf supported

config KCORE_ELF

        bool

        depends on PROC_FS

        default y

        help

          If you enabled support for /proc file system then the file

          /proc/kcore will contain the kernel core image in ELF format. This

          can be used in gdb:



          $ cd /usr/src/linux ; gdb vmlinux /proc/kcore



          This is especially useful if you have compiled the kernel with the

          "-g" option to preserve debugging information. It is mainly used

	  for examining kernel data structures on the live kernel.

	help

	  This is the filename of the ramdisk image to be built into the

	  kernel.  Relative pathnames are relative to arch/xtensa/boot/ramdisk/.

	  The ramdisk image is not part of the kernel distribution; you must

	  provide one yourself.
