199 bool "Enable setting the CPU clock frequency"
202 On some CPU's you do not need to know what the core CPU clock
203 frequency is. On these you can disable clock setting. On some
204 traditional 68K parts, and on all ColdFire parts you need to set
205 the appropriate CPU clock frequency. On these devices many of the
206 onboard peripherals derive their timing from the master CPU clock
210 int "Set the core clock frequency"
214 Define the CPU clock frequency in use. This is the core clock
215 frequency, it may or may not be the same as the external clock
216 crystal fitted to your board. Some processors have an internal
217 PLL and can have their frequency programmed at run time, others
218 use internal dividers. In general the kernel won't setup a PLL
219 if it is fitted (there are some exceptions). This value will be
220 specific to the exact CPU that you are using.
223 int "Set the core/bus clock divide ratio"
227 On many SoC style CPUs the master CPU clock is also used to drive
228 on-chip peripherals. The clock that is distributed to these
229 peripherals is sometimes a fixed ratio of the master clock
230 frequency. If so then set this to the divider ratio of the
231 master clock to the peripheral clock. If not sure then select 1.

552 If you say Y here the kernel will use a 4Kb stacksize for the
553 kernel stack attached to each process/thread. This facilitates
554 running more threads on a system and also reduces the pressure
555 on the VM subsystem for higher order allocations.

562 comment "RAM configuration"
565 hex "Address of the base of RAM"
568 Define the address that RAM starts at. On many platforms this is
569 0, the base of the address space. And this is the default. Some
570 platforms choose to setup their RAM at other addresses within the
571 processor address space.
574 hex "Size of RAM (in bytes), or 0 for automatic"
577 Define the size of the system RAM. If you select 0 then the
578 kernel will try to probe the RAM size at runtime. This is not
579 supported on all CPU types.
582 hex "Address of the base of system vectors"
585 Define the address of the system vectors. Commonly this is
586 put at the start of RAM, but it doesn't have to be. On ColdFire
587 platforms this address is programmed into the VBR register, thus
588 actually setting the address to use.
591 hex "Address of the base of kernel code"
594 Typically on m68k systems the kernel will not start at the base
595 of RAM, but usually some small offset from it. Define the start
596 address of the kernel here. The most common setup will have the
597 processor vectors at the base of RAM and then the start of the
598 kernel. On some platforms some RAM is reserved for boot loaders
599 and the kernel starts after that. The 0x400 default was based on
600 a system with the RAM based at address 0, and leaving enough room
601 for the theoretical maximum number of 256 vectors.
604 prompt "RAM bus width"
610 Select the physical RAM data bus size. Not needed on most platforms,
611 so you can generally choose AUTO.
616 Configure RAM bus to be 8 bits wide.
621 Configure RAM bus to be 16 bits wide.
626 Configure RAM bus to be 32 bits wide.
630 comment "ROM configuration"
633 bool "Specify ROM linker regions"
636 Define a ROM region for the linker script. This creates a kernel
637 that can be stored in flash, with possibly the text, and data
638 regions being copied out to RAM at startup.
641 hex "Address of the base of ROM device"
645 Define the address that the ROM region starts at. Some platforms
646 use this to set their chip select region accordingly for the boot
650 hex "Address of the base of the ROM vectors"
654 This is almost always the same as the base of the ROM. Since on all
655 68000 type variants the vectors are at the base of the boot device
659 hex "Size of ROM vector region (in bytes)"
663 Define the size of the vector region in ROM. For most 68000
664 variants this would be 0x400 bytes in size. Set to 0 if you do
665 not want a vector region at the start of the ROM.
668 hex "Address of the base of system image in ROM"
672 Define the start address of the system image in ROM. Commonly this
673 is strait after the ROM vectors.
676 hex "Size of the ROM device"
680 Size of the ROM device. On some platforms this is used to setup
681 the chip select that controls the boot ROM device.
684 prompt "Kernel executes from"
686 Choose the memory type that the kernel will be running in.
691 The kernel will be resident in RAM when running.
696 The kernel will be resident in FLASH/ROM when running. This is
697 often referred to as Execute-in-Place (XIP), since the kernel
698 code executes from the position it is stored in the FLASH/ROM.
