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

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

550 comment "RAM configuration"
553 hex "Address of the base of RAM"
556 Define the address that RAM starts at. On many platforms this is
557 0, the base of the address space. And this is the default. Some
558 platforms choose to setup their RAM at other addresses within the
559 processor address space.
562 hex "Size of RAM (in bytes)"
565 Define the size of the system RAM. If you select 0 then the
566 kernel will try to probe the RAM size at runtime. This is not
567 supported on all CPU types.
570 hex "Address of the base of system vectors"
573 Define the address of the system vectors. Commonly this is
574 put at the start of RAM, but it doesn't have to be. On ColdFire
575 platforms this address is programmed into the VBR register, thus
576 actually setting the address to use.
579 hex "Address of the base of kernel code"
582 Typically on m68k systems the kernel will not start at the base
583 of RAM, but usually some small offset from it. Define the start
584 address of the kernel here. The most common setup will have the
585 processor vectors at the base of RAM and then the start of the
586 kernel. On some platforms some RAM is reserved for boot loaders
587 and the kernel starts after that. The 0x400 default was based on
588 a system with the RAM based at address 0, and leaving enough room
589 for the theoretical maximum number of 256 vectors.
592 prompt "RAM bus width"
598 Select the physical RAM data bus size. Not needed on most platforms,
599 so you can generally choose AUTO.
604 Configure RAM bus to be 8 bits wide.
609 Configure RAM bus to be 16 bits wide.
614 Configure RAM bus to be 32 bits wide.
618 comment "ROM configuration"
621 bool "Specify ROM linker regions"
624 Define a ROM region for the linker script. This creates a kernel
625 that can be stored in flash, with possibly the text, and data
626 regions being copied out to RAM at startup.
629 hex "Address of the base of ROM device"
633 Define the address that the ROM region starts at. Some platforms
634 use this to set their chip select region accordingly for the boot
638 hex "Address of the base of the ROM vectors"
642 This is almost always the same as the base of the ROM. Since on all
643 68000 type variants the vectors are at the base of the boot device
647 hex "Size of ROM vector region (in bytes)"
651 Define the size of the vector region in ROM. For most 68000
652 variants this would be 0x400 bytes in size. Set to 0 if you do
653 not want a vector region at the start of the ROM.
656 hex "Address of the base of system image in ROM"
660 Define the start address of the system image in ROM. Commonly this
661 is strait after the ROM vectors.
664 hex "Size of the ROM device"
668 Size of the ROM device. On some platforms this is used to setup
669 the chip select that controls the boot ROM device.
672 prompt "Kernel executes from"
674 Choose the memory type that the kernel will be running in.
679 The kernel will be resident in RAM when running.
684 The kernel will be resident in FLASH/ROM when running. This is
685 often referred to as Execute-in-Place (XIP), since the kernel
686 code executes from the position it is stored in the FLASH/ROM.
