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

540 bool "Use 4Kb for kernel stacks instead of 8Kb"
543 If you say Y here the kernel will use a 4Kb stacksize for the
544 kernel stack attached to each process/thread. This facilitates
545 running more threads on a system and also reduces the pressure
546 on the VM subsystem for higher order allocations.

553 comment "RAM configuration"
556 hex "Address of the base of RAM"
559 Define the address that RAM starts at. On many platforms this is
560 0, the base of the address space. And this is the default. Some
561 platforms choose to setup their RAM at other addresses within the
562 processor address space.
565 hex "Size of RAM (in bytes), or 0 for automatic"
568 Define the size of the system RAM. If you select 0 then the
569 kernel will try to probe the RAM size at runtime. This is not
570 supported on all CPU types.
573 hex "Address of the base of system vectors"
576 Define the address of the system vectors. Commonly this is
577 put at the start of RAM, but it doesn't have to be. On ColdFire
578 platforms this address is programmed into the VBR register, thus
579 actually setting the address to use.
582 hex "Address of the base of kernel code"
585 Typically on m68k systems the kernel will not start at the base
586 of RAM, but usually some small offset from it. Define the start
587 address of the kernel here. The most common setup will have the
588 processor vectors at the base of RAM and then the start of the
589 kernel. On some platforms some RAM is reserved for boot loaders
590 and the kernel starts after that. The 0x400 default was based on
591 a system with the RAM based at address 0, and leaving enough room
592 for the theoretical maximum number of 256 vectors.
595 prompt "RAM bus width"
601 Select the physical RAM data bus size. Not needed on most platforms,
602 so you can generally choose AUTO.
607 Configure RAM bus to be 8 bits wide.
612 Configure RAM bus to be 16 bits wide.
617 Configure RAM bus to be 32 bits wide.
621 comment "ROM configuration"
624 bool "Specify ROM linker regions"
627 Define a ROM region for the linker script. This creates a kernel
628 that can be stored in flash, with possibly the text, and data
629 regions being copied out to RAM at startup.
632 hex "Address of the base of ROM device"
636 Define the address that the ROM region starts at. Some platforms
637 use this to set their chip select region accordingly for the boot
641 hex "Address of the base of the ROM vectors"
645 This is almost always the same as the base of the ROM. Since on all
646 68000 type variants the vectors are at the base of the boot device
650 hex "Size of ROM vector region (in bytes)"
654 Define the size of the vector region in ROM. For most 68000
655 variants this would be 0x400 bytes in size. Set to 0 if you do
656 not want a vector region at the start of the ROM.
659 hex "Address of the base of system image in ROM"
663 Define the start address of the system image in ROM. Commonly this
664 is strait after the ROM vectors.
667 hex "Size of the ROM device"
671 Size of the ROM device. On some platforms this is used to setup
672 the chip select that controls the boot ROM device.
675 prompt "Kernel executes from"
677 Choose the memory type that the kernel will be running in.
682 The kernel will be resident in RAM when running.
687 The kernel will be resident in FLASH/ROM when running. This is
688 often referred to as Execute-in-Place (XIP), since the kernel
689 code executes from the position it is stored in the FLASH/ROM.
