It affects the instruction set used. config MN10300_CPU_AM33V2 bool "AM33v2" endchoice config FPU bool "FPU present" default y depends on MN10300_PROC_MN103E010 choice 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 MN10300_CACHE_WBACK bool "Write-Back" config MN10300_CACHE_WTHRU bool "Write-Through" config MN10300_CACHE_DISABLED bool "Disabled" endchoice menu "Memory layout options" config KERNEL_RAM_BASE_ADDRESS hex "Base address of kernel RAM" default "0x90000000" config INTERRUPT_VECTOR_BASE hex "Base address of vector table" default "0x90000000" help The base address of the vector table will be programmed into the TBR register. It must be on 16MiB address boundary. config KERNEL_TEXT_ADDRESS hex "Base address of kernel" default "0x90001000" config KERNEL_ZIMAGE_BASE_ADDRESS hex "Base address of compressed vmlinux image" default "0x90700000" endmenu 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 bool "Using MN10300 RTC" depends on MN10300_PROC_MN103E010 default n help 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. config MN10300_WD_TIMER bool "Using MN10300 watchdog timer" default y help 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 , contains valuable information about which PCI hardware does work under Linux and which doesn't. source "drivers/pci/Kconfig" source "drivers/pcmcia/Kconfig" menu "MN10300 internal serial options" config MN10300_PROC_HAS_TTYSM0 bool default n config MN10300_PROC_HAS_TTYSM1 bool default n config MN10300_PROC_HAS_TTYSM2 bool default n config MN10300_TTYSM bool "Support for ttySM serial ports" depends on MN10300 default y select SERIAL_CORE help This option enables support for the on-chip serial ports that the MN10300 has available. config MN10300_TTYSM_CONSOLE bool "Support for console on ttySM serial ports" depends on MN10300_TTYSM select SERIAL_CORE_CONSOLE help This option enables support for a console on the on-chip serial ports that the MN10300 has available. # # /dev/ttySM0 # config MN10300_TTYSM0 bool "Enable SIF0 (/dev/ttySM0)" depends on MN10300_TTYSM && MN10300_PROC_HAS_TTYSM0 help Enable access to SIF0 through /dev/ttySM0 or gdb-stub choice prompt "Select the timer to supply the clock for SIF0" default MN10300_TTYSM0_TIMER8 depends on MN10300_TTYSM0 config MN10300_TTYSM0_TIMER8 bool "Use timer 8 (16-bit)" config MN10300_TTYSM0_TIMER2 bool "Use timer 2 (8-bit)" endchoice # # /dev/ttySM1 # config MN10300_TTYSM1 bool "Enable SIF1 (/dev/ttySM1)" depends on MN10300_TTYSM && MN10300_PROC_HAS_TTYSM1 help Enable access to SIF1 through /dev/ttySM1 or gdb-stub choice prompt "Select the timer to supply the clock for SIF1" default MN10300_TTYSM0_TIMER9 depends on MN10300_TTYSM1 config MN10300_TTYSM1_TIMER9 bool "Use timer 9 (16-bit)" config MN10300_TTYSM1_TIMER3 bool "Use timer 3 (8-bit)" endchoice # # /dev/ttySM2 # config MN10300_TTYSM2 bool "Enable SIF2 (/dev/ttySM2)" depends on MN10300_TTYSM && MN10300_PROC_HAS_TTYSM2 help Enable access to SIF2 through /dev/ttySM2 or gdb-stub choice prompt "Select the timer to supply the clock for SIF2" default MN10300_TTYSM0_TIMER10 depends on MN10300_TTYSM2 config MN10300_TTYSM2_TIMER10 bool "Use timer 10 (16-bit)" endchoice config MN10300_TTYSM2_CTS bool "Enable the use of the CTS line /dev/ttySM2" depends on MN10300_TTYSM2 endmenu source "mm/Kconfig" menu "Power management options" source kernel/power/Kconfig endmenu endmenu menu "Executable formats" source "fs/Kconfig.binfmt" endmenu source "net/Kconfig" source "drivers/Kconfig" source "fs/Kconfig" source "arch/mn10300/Kconfig.debug" source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig"
