More information (hardware only) at <http://www.hp.com/jornada/>. config SH_CQREEK bool "CqREEK" help Select CqREEK if configuring for a CqREEK SH7708 or SH7750. More information at <http://sources.redhat.com/ecos/hardware.html#SuperH>. config SH_DMIDA bool "DMIDA" help Select DMIDA if configuring for a DataMyte 4000 Industrial Digital Assistant. More information at <http://www.dmida.com/>. config SH_EC3104 bool "EC3104" help Select EC3104 if configuring for a system with an Eclipse International EC3104 chip, e.g. the Harris AD2000. config SH_SATURN bool "Saturn" select CPU_SUBTYPE_SH7604 help Select Saturn if configuring for a SEGA Saturn. config SH_DREAMCAST bool "Dreamcast" select CPU_SUBTYPE_SH7091 help Select Dreamcast if configuring for a SEGA Dreamcast. More information at <http://www.m17n.org/linux-sh/dreamcast/>. There is a Dreamcast project is at <http://linuxdc.sourceforge.net/>. config SH_CAT68701 bool "CAT68701" config SH_BIGSUR bool "BigSur" config SH_SH2000 bool "SH2000" select CPU_SUBTYPE_SH7709 help SH-2000 is a single-board computer based around SH7709A chip intended for embedded applications. It has an Ethernet interface (CS8900A), direct connected Compact Flash socket, three serial ports and PC-104 bus. More information at <http://sh2000.sh-linux.org>. config SH_ADX bool "ADX" config SH_MPC1211 bool "Interface MPC1211" help CTP/PCI-SH02 is a CPU module computer that is produced by Interface Corporation. More information at <http://www.interface.co.jp> config SH_SH03 bool "Interface CTP/PCI-SH03" help CTP/PCI-SH03 is a CPU module computer that is produced by Interface Corporation. More information at <http://www.interface.co.jp> config SH_SECUREEDGE5410 bool "SecureEdge5410" select CPU_SUBTYPE_SH7751R help Select SecureEdge5410 if configuring for a SnapGear SH board. This includes both the OEM SecureEdge products as well as the SME product line. config SH_HS7751RVOIP bool "HS7751RVOIP" select CPU_SUBTYPE_SH7751R help Select HS7751RVOIP if configuring for a Renesas Technology Sales VoIP board. config SH_RTS7751R2D bool "RTS7751R2D" select CPU_SUBTYPE_SH7751R help Select RTS7751R2D if configuring for a Renesas Technology Sales SH-Graphics board. config SH_R7780RP bool "R7780RP-1" select CPU_SUBTYPE_SH7780 help Select R7780RP-1 if configuring for a Renesas Solutions HIGHLANDER board. config SH_EDOSK7705 bool "EDOSK7705" select CPU_SUBTYPE_SH7705 config SH_SH4202_MICRODEV bool "SH4-202 MicroDev" select CPU_SUBTYPE_SH4_202 help Select SH4-202 MicroDev if configuring for a SuperH MicroDev board with an SH4-202 CPU. config SH_LANDISK bool "LANDISK" select CPU_SUBTYPE_SH7751R help I-O DATA DEVICE, INC. "LANDISK Series" support. config SH_TITAN bool "TITAN" select CPU_SUBTYPE_SH7751R help Select Titan if you are configuring for a Nimble Microsystems NetEngine NP51R. 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. endchoice source "arch/sh/mm/Kconfig" 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. config CF_ENABLER bool "Compact Flash Enabler support" depends on SH_ADX || SH_SOLUTION_ENGINE || SH_UNKNOWN || SH_CAT68701 || SH_SH03 ---help--- 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'. choice prompt "Compact Flash Connection Area" depends on CF_ENABLER default CF_AREA6 config CF_AREA5 bool "Area5" help If your board has "Directly Connected" CompactFlash, You should select the area where your CF is connected to. - "Area5" if CompactFlash is connected to Area 5 (0x14000000) - "Area6" if it is connected to Area 6 (0x18000000) "Area6" will work for most boards. For ADX, select "Area5". config CF_AREA6 bool "Area6" endchoice config CF_BASE_ADDR hex depends on CF_ENABLER default "0xb8000000" if CF_AREA6 default "0xb4000000" if CF_AREA5 menu "Processor features" config CPU_LITTLE_ENDIAN bool "Little Endian" help Some SuperH machines can be configured for either little or big endian byte order. These modes require different kernels. Say Y if your machine is little endian, N if it's a big endian machine. # The SH7750 RTC module is disabled in the Dreamcast config SH_RTC bool depends on !SH_DREAMCAST && !SH_SATURN && !SH_7300_SOLUTION_ENGINE && \ !SH_73180_SOLUTION_ENGINE && !SH_LANDISK && \ !SH_R7780RP default y help Selecting this option will allow the Linux kernel to emulate PC's RTC. If unsure, say N. config SH_FPU bool "FPU support" depends on !CPU_SH3 default y help Selecting this option will enable support for SH processors that have FPU units (ie, SH77xx). This option must be set in order to enable the FPU. config SH_DSP bool "DSP support" depends on !CPU_SH4 default y help Selecting this option will enable support for SH processors that have DSP units (ie, SH2-DSP and SH3-DSP). It is safe to say Y here by default, as the existance of the DSP will be probed at runtime. This option must be set in order to enable the DSP. config SH_ADC bool "ADC support" depends on CPU_SH3 default y help Selecting this option will allow the Linux kernel to use SH3 on-chip ADC module. If unsure, say N. config SH_STORE_QUEUES bool "Support for Store Queues" depends on CPU_SH4 help Selecting this option will enable an in-kernel API for manipulating the store queues integrated in the SH-4 processors. config CPU_HAS_INTEVT bool config CPU_HAS_PINT_IRQ bool config CPU_HAS_INTC2_IRQ bool config CPU_HAS_SR_RB bool "CPU has SR.RB" depends on CPU_SH3 || CPU_SH4 default y help This will enable the use of SR.RB register bank usage. Processors that are lacking this bit must have another method in place for accomplishing what is taken care of by the banked registers. See <file:Documentation/sh/register-banks.txt> for further information on SR.RB and register banking in the kernel in general. endmenu menu "Timer support" config SH_TMU bool "TMU timer support" default y help This enables the use of the TMU as the system timer. endmenu #source "arch/sh/boards/renesas/hs7751rvoip/Kconfig" #source "arch/sh/boards/renesas/rts7751r2d/Kconfig" config SH_PCLK_FREQ int "Peripheral clock frequency (in Hz)" default "50000000" if CPU_SUBTYPE_SH7750 || CPU_SUBTYPE_SH7780 default "60000000" if CPU_SUBTYPE_SH7751 default "33333333" if CPU_SUBTYPE_SH7300 || CPU_SUBTYPE_SH7770 || CPU_SUBTYPE_SH7760 default "27000000" if CPU_SUBTYPE_SH73180 default "66000000" if CPU_SUBTYPE_SH4_202 help This option is used to specify the peripheral clock frequency. This is necessary for determining the reference clock value on platforms lacking an RTC. menu "CPU Frequency scaling" source "drivers/cpufreq/Kconfig" config SH_CPU_FREQ tristate "SuperH CPU Frequency driver" depends on CPU_FREQ select CPU_FREQ_TABLE help This adds the cpufreq driver for SuperH. At present, only the SH-4 is supported. For details, take a look at <file:Documentation/cpu-freq>. If unsure, say N. endmenu source "arch/sh/drivers/dma/Kconfig" source "arch/sh/cchips/Kconfig" config HEARTBEAT bool "Heartbeat LED" depends on SH_MPC1211 || SH_SH03 || SH_CAT68701 || \ SH_STB1_HARP || SH_STB1_OVERDRIVE || SH_BIGSUR || \ SH_7751_SOLUTION_ENGINE || SH_7300_SOLUTION_ENGINE || \ SH_73180_SOLUTION_ENGINE || SH_SOLUTION_ENGINE || \ SH_RTS7751R2D || SH_SH4202_MICRODEV || SH_LANDISK help Use the power-on LED on your machine as a load meter. The exact behavior is platform-dependent, but normally the flash frequency is a hyperbolic function of the 5-minute load average. endmenu config ISA_DMA_API bool depends on SH_MPC1211 default y menu "Kernel features" config KEXEC bool "kexec system call (EXPERIMENTAL)" depends on 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)" depends on 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. config NR_CPUS int "Maximum number of CPUs (2-32)" range 2 32 depends on SMP default "2" 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. config CPU_HAS_SR_RB bool "CPU has SR.RB" depends on CPU_SH3 || CPU_SH4 default y help This will enable the use of SR.RB register bank usage. Processors that are lacking this bit must have another method in place for accomplishing what is taken care of by the banked registers. See <file:Documentation/sh/register-banks.txt> for further information on SR.RB and register banking in the kernel in general. config NODES_SHIFT int default "1" depends on NEED_MULTIPLE_NODES endmenu menu "Boot options" config ZERO_PAGE_OFFSET hex "Zero page offset" default "0x00004000" if SH_MPC1211 || SH_SH03 default "0x00001000" help This sets the default offset of zero page. config BOOT_LINK_OFFSET hex "Link address offset for booting" default "0x00800000" help This option allows you to set the link address offset of the zImage. This can be useful if you are on a board which has a small amount of memory. config UBC_WAKEUP bool "Wakeup UBC on startup" 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 comes up, some boot loaders misbehave by putting the UBC to sleep in a power saving state, which causes issues with things like ptrace(). If unsure, say N. config CMDLINE_BOOL bool "Default bootloader kernel arguments" config CMDLINE string "Initial kernel command string" depends on CMDLINE_BOOL default "console=ttySC1,115200" endmenu menu "Bus options" # Even on SuperH devices which don't have an ISA bus, # this variable helps the PCMCIA modules handle # IRQ requesting properly -- Greg Banks. # # Though we're generally not interested in it when # we're not using PCMCIA, so we make it dependent on # PCMCIA outright. -- PFM. config ISA bool default y if PCMCIA 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. config MCA bool help MicroChannel Architecture is found in some IBM PS/2 machines and laptops. It is a bus system similar to PCI or ISA. See <file:Documentation/mca.txt> (and especially the web page given there) before attempting to build an MCA bus kernel. config SBUS bool config SUPERHYWAY tristate "SuperHyway Bus support" depends on CPU_SUBTYPE_SH4_202 source "arch/sh/drivers/pci/Kconfig" source "drivers/pci/Kconfig" source "drivers/pcmcia/Kconfig" source "drivers/pci/hotplug/Kconfig" endmenu menu "Executable file formats" source "fs/Kconfig.binfmt" endmenu source "net/Kconfig" source "drivers/Kconfig" source "fs/Kconfig" source "arch/sh/oprofile/Kconfig" source "arch/sh/Kconfig.debug" source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig"
