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

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

534 comment "RAM configuration"
537 hex "Address of the base of RAM"
540 Define the address that RAM starts at. On many platforms this is
541 0, the base of the address space. And this is the default. Some
542 platforms choose to setup their RAM at other addresses within the
543 processor address space.
546 hex "Size of RAM (in bytes)"
549 Define the size of the system RAM. If you select 0 then the
550 kernel will try to probe the RAM size at runtime. This is not
551 supported on all CPU types.
554 hex "Address of the base of system vectors"
557 Define the address of the system vectors. Commonly this is
558 put at the start of RAM, but it doesn't have to be. On ColdFire
559 platforms this address is programmed into the VBR register, thus
560 actually setting the address to use.
563 hex "Address of the base of kernel code"
566 Typically on m68k systems the kernel will not start at the base
567 of RAM, but usually some small offset from it. Define the start
568 address of the kernel here. The most common setup will have the
569 processor vectors at the base of RAM and then the start of the
570 kernel. On some platforms some RAM is reserved for boot loaders
571 and the kernel starts after that. The 0x400 default was based on
572 a system with the RAM based at address 0, and leaving enough room
573 for the theoretical maximum number of 256 vectors.
576 prompt "RAM bus width"
582 Select the physical RAM data bus size. Not needed on most platforms,
583 so you can generally choose AUTO.
588 Configure RAM bus to be 8 bits wide.
593 Configure RAM bus to be 16 bits wide.
598 Configure RAM bus to be 32 bits wide.
602 comment "ROM configuration"
605 bool "Specify ROM linker regions"
608 Define a ROM region for the linker script. This creates a kernel
609 that can be stored in flash, with possibly the text, and data
610 regions being copied out to RAM at startup.
613 hex "Address of the base of ROM device"
617 Define the address that the ROM region starts at. Some platforms
618 use this to set their chip select region accordingly for the boot
622 hex "Address of the base of the ROM vectors"
626 This is almost always the same as the base of the ROM. Since on all
627 68000 type variants the vectors are at the base of the boot device
631 hex "Size of ROM vector region (in bytes)"
635 Define the size of the vector region in ROM. For most 68000
636 variants this would be 0x400 bytes in size. Set to 0 if you do
637 not want a vector region at the start of the ROM.
640 hex "Address of the base of system image in ROM"
644 Define the start address of the system image in ROM. Commonly this
645 is strait after the ROM vectors.
648 hex "Size of the ROM device"
652 Size of the ROM device. On some platforms this is used to setup
653 the chip select that controls the boot ROM device.
656 prompt "Kernel executes from"
658 Choose the memory type that the kernel will be running in.
663 The kernel will be resident in RAM when running.
668 The kernel will be resident in FLASH/ROM when running. This is
669 often referred to as Execute-in-Place (XIP), since the kernel
670 code executes from the position it is stored in the FLASH/ROM.
