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

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

549 comment "RAM configuration"
552 hex "Address of the base of RAM"
555 Define the address that RAM starts at. On many platforms this is
556 0, the base of the address space. And this is the default. Some
557 platforms choose to setup their RAM at other addresses within the
558 processor address space.
561 hex "Size of RAM (in bytes)"
564 Define the size of the system RAM. If you select 0 then the
565 kernel will try to probe the RAM size at runtime. This is not
566 supported on all CPU types.
569 hex "Address of the base of system vectors"
572 Define the address of the system vectors. Commonly this is
573 put at the start of RAM, but it doesn't have to be. On ColdFire
574 platforms this address is programmed into the VBR register, thus
575 actually setting the address to use.
578 hex "Address of the base of kernel code"
581 Typically on m68k systems the kernel will not start at the base
582 of RAM, but usually some small offset from it. Define the start
583 address of the kernel here. The most common setup will have the
584 processor vectors at the base of RAM and then the start of the
585 kernel. On some platforms some RAM is reserved for boot loaders
586 and the kernel starts after that. The 0x400 default was based on
587 a system with the RAM based at address 0, and leaving enough room
588 for the theoretical maximum number of 256 vectors.
591 prompt "RAM bus width"
597 Select the physical RAM data bus size. Not needed on most platforms,
598 so you can generally choose AUTO.
603 Configure RAM bus to be 8 bits wide.
608 Configure RAM bus to be 16 bits wide.
613 Configure RAM bus to be 32 bits wide.
617 comment "ROM configuration"
620 bool "Specify ROM linker regions"
623 Define a ROM region for the linker script. This creates a kernel
624 that can be stored in flash, with possibly the text, and data
625 regions being copied out to RAM at startup.
628 hex "Address of the base of ROM device"
632 Define the address that the ROM region starts at. Some platforms
633 use this to set their chip select region accordingly for the boot
637 hex "Address of the base of the ROM vectors"
641 This is almost always the same as the base of the ROM. Since on all
642 68000 type variants the vectors are at the base of the boot device
646 hex "Size of ROM vector region (in bytes)"
650 Define the size of the vector region in ROM. For most 68000
651 variants this would be 0x400 bytes in size. Set to 0 if you do
652 not want a vector region at the start of the ROM.
655 hex "Address of the base of system image in ROM"
659 Define the start address of the system image in ROM. Commonly this
660 is strait after the ROM vectors.
663 hex "Size of the ROM device"
667 Size of the ROM device. On some platforms this is used to setup
668 the chip select that controls the boot ROM device.
671 prompt "Kernel executes from"
673 Choose the memory type that the kernel will be running in.
678 The kernel will be resident in RAM when running.
683 The kernel will be resident in FLASH/ROM when running. This is
684 often referred to as Execute-in-Place (XIP), since the kernel
685 code executes from the position it is stored in the FLASH/ROM.
