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.

502 bool "Use 4Kb for kernel stacks instead of 8Kb"
505 If you say Y here the kernel will use a 4Kb stacksize for the
506 kernel stack attached to each process/thread. This facilitates
507 running more threads on a system and also reduces the pressure
508 on the VM subsystem for higher order allocations.
510 comment "RAM configuration"
513 hex "Address of the base of RAM"
516 Define the address that RAM starts at. On many platforms this is
517 0, the base of the address space. And this is the default. Some
518 platforms choose to setup their RAM at other addresses within the
519 processor address space.
522 hex "Size of RAM (in bytes)"
525 Define the size of the system RAM. If you select 0 then the
526 kernel will try to probe the RAM size at runtime. This is not
527 supported on all CPU types.
530 hex "Address of the base of system vectors"
533 Define the address of the system vectors. Commonly this is
534 put at the start of RAM, but it doesn't have to be. On ColdFire
535 platforms this address is programmed into the VBR register, thus
536 actually setting the address to use.
539 hex "Address of the base of kernel code"
542 Typically on m68k systems the kernel will not start at the base
543 of RAM, but usually some small offset from it. Define the start
544 address of the kernel here. The most common setup will have the
545 processor vectors at the base of RAM and then the start of the
546 kernel. On some platforms some RAM is reserved for boot loaders
547 and the kernel starts after that. The 0x400 default was based on
548 a system with the RAM based at address 0, and leaving enough room
549 for the theoretical maximum number of 256 vectors.
552 prompt "RAM bus width"
558 Select the physical RAM data bus size. Not needed on most platforms,
559 so you can generally choose AUTO.
564 Configure RAM bus to be 8 bits wide.
569 Configure RAM bus to be 16 bits wide.
574 Configure RAM bus to be 32 bits wide.
578 comment "ROM configuration"
581 bool "Specify ROM linker regions"
584 Define a ROM region for the linker script. This creates a kernel
585 that can be stored in flash, with possibly the text, and data
586 regions being copied out to RAM at startup.
589 hex "Address of the base of ROM device"
593 Define the address that the ROM region starts at. Some platforms
594 use this to set their chip select region accordingly for the boot
598 hex "Address of the base of the ROM vectors"
602 This is almost always the same as the base of the ROM. Since on all
603 68000 type variants the vectors are at the base of the boot device
607 hex "Size of ROM vector region (in bytes)"
611 Define the size of the vector region in ROM. For most 68000
612 variants this would be 0x400 bytes in size. Set to 0 if you do
613 not want a vector region at the start of the ROM.
616 hex "Address of the base of system image in ROM"
620 Define the start address of the system image in ROM. Commonly this
621 is strait after the ROM vectors.
624 hex "Size of the ROM device"
628 Size of the ROM device. On some platforms this is used to setup
629 the chip select that controls the boot ROM device.
632 prompt "Kernel executes from"
634 Choose the memory type that the kernel will be running in.
639 The kernel will be resident in RAM when running.
644 The kernel will be resident in FLASH/ROM when running. This is
645 often referred to as Execute-in-Place (XIP), since the kernel
646 code executes from the position it is stored in the FLASH/ROM.
