On these you can disable clock setting. On some traditional 68K parts, and on all ColdFire parts you need to set the appropriate CPU clock frequency. On these devices many of the onboard peripherals derive their timing from the master CPU clock frequency. config CLOCK_FREQ int "Set the core clock frequency" default "66666666" depends on CLOCK_SET help Define the CPU clock frequency in use. This is the core clock frequency, it may or may not be the same as the external clock crystal fitted to your board. Some processors have an internal PLL and can have their frequency programmed at run time, others use internal dividers. In general the kernel won't setup a PLL if it is fitted (there are some exceptions). This value will be specific to the exact CPU that you are using. config CLOCK_DIV int "Set the core/bus clock divide ratio" default "1" depends on CLOCK_SET help On many SoC style CPUs the master CPU clock is also used to drive on-chip peripherals. The clock that is distributed to these peripherals is sometimes a fixed ratio of the master clock frequency. If so then set this to the divider ratio of the master clock to the peripheral clock.

This facilitates running more threads on a system and also reduces the pressure on the VM subsystem for higher order allocations. comment "RAM configuration" config RAMBASE hex "Address of the base of RAM" default "0" help Define the address that RAM starts at. On many platforms this is 0, the base of the address space. And this is the default. Some platforms choose to setup their RAM at other addresses within the processor address space. config RAMSIZE hex "Size of RAM (in bytes)" default "0x400000" help Define the size of the system RAM. If you select 0 then the kernel will try to probe the RAM size at runtime. This is not supported on all CPU types. config VECTORBASE hex "Address of the base of system vectors" default "0" help Define the address of the system vectors. Commonly this is put at the start of RAM, but it doesn't have to be. On ColdFire platforms this address is programmed into the VBR register, thus actually setting the address to use. config KERNELBASE hex "Address of the base of kernel code" default "0x400" help Typically on m68k systems the kernel will not start at the base of RAM, but usually some small offset from it. Define the start address of the kernel here. The most common setup will have the processor vectors at the base of RAM and then the start of the kernel. On some platforms some RAM is reserved for boot loaders and the kernel starts after that. The 0x400 default was based on a system with the RAM based at address 0, and leaving enough room for the theoretical maximum number of 256 vectors. choice prompt "RAM bus width" default RAMAUTOBIT config RAMAUTOBIT bool "AUTO" help Select the physical RAM data bus size. Not needed on most platforms, so you can generally choose AUTO. config RAM8BIT bool "8bit" help Configure RAM bus to be 8 bits wide. config RAM16BIT bool "16bit" help Configure RAM bus to be 16 bits wide. config RAM32BIT bool "32bit" help Configure RAM bus to be 32 bits wide. endchoice comment "ROM configuration" config ROM bool "Specify ROM linker regions" default n help Define a ROM region for the linker script. This creates a kernel that can be stored in flash, with possibly the text, and data regions being copied out to RAM at startup. config ROMBASE hex "Address of the base of ROM device" default "0" depends on ROM help Define the address that the ROM region starts at. Some platforms use this to set their chip select region accordingly for the boot device. config ROMVEC hex "Address of the base of the ROM vectors" default "0" depends on ROM help This is almost always the same as the base of the ROM. Since on all 68000 type variants the vectors are at the base of the boot device on system startup. config ROMVECSIZE hex "Size of ROM vector region (in bytes)" default "0x400" depends on ROM help Define the size of the vector region in ROM. For most 68000 variants this would be 0x400 bytes in size. Set to 0 if you do not want a vector region at the start of the ROM. config ROMSTART hex "Address of the base of system image in ROM" default "0x400" depends on ROM help Define the start address of the system image in ROM. Commonly this is strait after the ROM vectors. config ROMSIZE hex "Size of the ROM device" default "0x100000" depends on ROM help Size of the ROM device. On some platforms this is used to setup the chip select that controls the boot ROM device. choice prompt "Kernel executes from" ---help--- Choose the memory type that the kernel will be running in. config RAMKERNEL bool "RAM" help The kernel will be resident in RAM when running. config ROMKERNEL bool "ROM" help The kernel will be resident in FLASH/ROM when running. This is often referred to as Execute-in-Place (XIP), since the kernel code executes from the position it is stored in the FLASH/ROM. endchoice source "mm/Kconfig" endmenu config ISA_DMA_API bool depends on !M5272 default y menu "Bus options (PCI, PCMCIA, EISA, MCA, ISA)" config PCI bool "PCI support" help Support for PCI bus. config COMEMPCI bool "CO-MEM lite PCI controller support" depends on (M5307 || M5407) source "drivers/pci/Kconfig" source "drivers/pcmcia/Kconfig" source "drivers/pci/hotplug/Kconfig" endmenu menu "Executable file formats" source "fs/Kconfig.binfmt" endmenu menu "Power management options" config PM bool "Power Management support" help Support processor power management modes endmenu source "net/Kconfig" source "drivers/Kconfig" source "fs/Kconfig" source "arch/m68knommu/Kconfig.debug" source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig"
