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

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

533 comment "RAM configuration"
536 hex "Address of the base of RAM"
539 Define the address that RAM starts at. On many platforms this is
540 0, the base of the address space. And this is the default. Some
541 platforms choose to setup their RAM at other addresses within the
542 processor address space.
545 hex "Size of RAM (in bytes)"
548 Define the size of the system RAM. If you select 0 then the
549 kernel will try to probe the RAM size at runtime. This is not
550 supported on all CPU types.
553 hex "Address of the base of system vectors"
556 Define the address of the system vectors. Commonly this is
557 put at the start of RAM, but it doesn't have to be. On ColdFire
558 platforms this address is programmed into the VBR register, thus
559 actually setting the address to use.
562 hex "Address of the base of kernel code"
565 Typically on m68k systems the kernel will not start at the base
566 of RAM, but usually some small offset from it. Define the start
567 address of the kernel here. The most common setup will have the
568 processor vectors at the base of RAM and then the start of the
569 kernel. On some platforms some RAM is reserved for boot loaders
570 and the kernel starts after that. The 0x400 default was based on
571 a system with the RAM based at address 0, and leaving enough room
572 for the theoretical maximum number of 256 vectors.
575 prompt "RAM bus width"
581 Select the physical RAM data bus size. Not needed on most platforms,
582 so you can generally choose AUTO.
587 Configure RAM bus to be 8 bits wide.
592 Configure RAM bus to be 16 bits wide.
597 Configure RAM bus to be 32 bits wide.
601 comment "ROM configuration"
604 bool "Specify ROM linker regions"
607 Define a ROM region for the linker script. This creates a kernel
608 that can be stored in flash, with possibly the text, and data
609 regions being copied out to RAM at startup.
612 hex "Address of the base of ROM device"
616 Define the address that the ROM region starts at. Some platforms
617 use this to set their chip select region accordingly for the boot
621 hex "Address of the base of the ROM vectors"
625 This is almost always the same as the base of the ROM. Since on all
626 68000 type variants the vectors are at the base of the boot device
630 hex "Size of ROM vector region (in bytes)"
634 Define the size of the vector region in ROM. For most 68000
635 variants this would be 0x400 bytes in size. Set to 0 if you do
636 not want a vector region at the start of the ROM.
639 hex "Address of the base of system image in ROM"
643 Define the start address of the system image in ROM. Commonly this
644 is strait after the ROM vectors.
647 hex "Size of the ROM device"
651 Size of the ROM device. On some platforms this is used to setup
652 the chip select that controls the boot ROM device.
655 prompt "Kernel executes from"
657 Choose the memory type that the kernel will be running in.
662 The kernel will be resident in RAM when running.
667 The kernel will be resident in FLASH/ROM when running. This is
668 often referred to as Execute-in-Place (XIP), since the kernel
669 code executes from the position it is stored in the FLASH/ROM.
