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

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

538 comment "RAM configuration"
541 hex "Address of the base of RAM"
544 Define the address that RAM starts at. On many platforms this is
545 0, the base of the address space. And this is the default. Some
546 platforms choose to setup their RAM at other addresses within the
547 processor address space.
550 hex "Size of RAM (in bytes)"
553 Define the size of the system RAM. If you select 0 then the
554 kernel will try to probe the RAM size at runtime. This is not
555 supported on all CPU types.
558 hex "Address of the base of system vectors"
561 Define the address of the system vectors. Commonly this is
562 put at the start of RAM, but it doesn't have to be. On ColdFire
563 platforms this address is programmed into the VBR register, thus
564 actually setting the address to use.
567 hex "Address of the base of kernel code"
570 Typically on m68k systems the kernel will not start at the base
571 of RAM, but usually some small offset from it. Define the start
572 address of the kernel here. The most common setup will have the
573 processor vectors at the base of RAM and then the start of the
574 kernel. On some platforms some RAM is reserved for boot loaders
575 and the kernel starts after that. The 0x400 default was based on
576 a system with the RAM based at address 0, and leaving enough room
577 for the theoretical maximum number of 256 vectors.
580 prompt "RAM bus width"
586 Select the physical RAM data bus size. Not needed on most platforms,
587 so you can generally choose AUTO.
592 Configure RAM bus to be 8 bits wide.
597 Configure RAM bus to be 16 bits wide.
602 Configure RAM bus to be 32 bits wide.
606 comment "ROM configuration"
609 bool "Specify ROM linker regions"
612 Define a ROM region for the linker script. This creates a kernel
613 that can be stored in flash, with possibly the text, and data
614 regions being copied out to RAM at startup.
617 hex "Address of the base of ROM device"
621 Define the address that the ROM region starts at. Some platforms
622 use this to set their chip select region accordingly for the boot
626 hex "Address of the base of the ROM vectors"
630 This is almost always the same as the base of the ROM. Since on all
631 68000 type variants the vectors are at the base of the boot device
635 hex "Size of ROM vector region (in bytes)"
639 Define the size of the vector region in ROM. For most 68000
640 variants this would be 0x400 bytes in size. Set to 0 if you do
641 not want a vector region at the start of the ROM.
644 hex "Address of the base of system image in ROM"
648 Define the start address of the system image in ROM. Commonly this
649 is strait after the ROM vectors.
652 hex "Size of the ROM device"
656 Size of the ROM device. On some platforms this is used to setup
657 the chip select that controls the boot ROM device.
660 prompt "Kernel executes from"
662 Choose the memory type that the kernel will be running in.
667 The kernel will be resident in RAM when running.
672 The kernel will be resident in FLASH/ROM when running. This is
673 often referred to as Execute-in-Place (XIP), since the kernel
674 code executes from the position it is stored in the FLASH/ROM.
