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

478 bool "Use 4Kb for kernel stacks instead of 8Kb"
481 If you say Y here the kernel will use a 4Kb stacksize for the
482 kernel stack attached to each process/thread. This facilitates
483 running more threads on a system and also reduces the pressure
484 on the VM subsystem for higher order allocations.
486 comment "RAM configuration"
489 hex "Address of the base of RAM"
492 Define the address that RAM starts at. On many platforms this is
493 0, the base of the address space. And this is the default. Some
494 platforms choose to setup their RAM at other addresses within the
495 processor address space.
498 hex "Size of RAM (in bytes)"
501 Define the size of the system RAM. If you select 0 then the
502 kernel will try to probe the RAM size at runtime. This is not
503 supported on all CPU types.
506 hex "Address of the base of system vectors"
509 Define the address of the system vectors. Commonly this is
510 put at the start of RAM, but it doesn't have to be. On ColdFire
511 platforms this address is programmed into the VBR register, thus
512 actually setting the address to use.
515 hex "Address of the base of kernel code"
518 Typically on m68k systems the kernel will not start at the base
519 of RAM, but usually some small offset from it. Define the start
520 address of the kernel here. The most common setup will have the
521 processor vectors at the base of RAM and then the start of the
522 kernel. On some platforms some RAM is reserved for boot loaders
523 and the kernel starts after that. The 0x400 default was based on
524 a system with the RAM based at address 0, and leaving enough room
525 for the theoretical maximum number of 256 vectors.
528 prompt "RAM bus width"
534 Select the physical RAM data bus size. Not needed on most platforms,
535 so you can generally choose AUTO.
540 Configure RAM bus to be 8 bits wide.
545 Configure RAM bus to be 16 bits wide.
550 Configure RAM bus to be 32 bits wide.
554 comment "ROM configuration"
557 bool "Specify ROM linker regions"
560 Define a ROM region for the linker script. This creates a kernel
561 that can be stored in flash, with possibly the text, and data
562 regions being copied out to RAM at startup.
565 hex "Address of the base of ROM device"
569 Define the address that the ROM region starts at. Some platforms
570 use this to set their chip select region accordingly for the boot
574 hex "Address of the base of the ROM vectors"
578 This is almost always the same as the base of the ROM. Since on all
579 68000 type variants the vectors are at the base of the boot device
583 hex "Size of ROM vector region (in bytes)"
587 Define the size of the vector region in ROM. For most 68000
588 variants this would be 0x400 bytes in size. Set to 0 if you do
589 not want a vector region at the start of the ROM.
592 hex "Address of the base of system image in ROM"
596 Define the start address of the system image in ROM. Commonly this
597 is strait after the ROM vectors.
600 hex "Size of the ROM device"
604 Size of the ROM device. On some platforms this is used to setup
605 the chip select that controls the boot ROM device.
608 prompt "Kernel executes from"
610 Choose the memory type that the kernel will be running in.
615 The kernel will be resident in RAM when running.
620 The kernel will be resident in FLASH/ROM when running. This is
621 often referred to as Execute-in-Place (XIP), since the kernel
622 code executes from the position it is stored in the FLASH/ROM.
