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

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

545 comment "RAM configuration"
548 hex "Address of the base of RAM"
551 Define the address that RAM starts at. On many platforms this is
552 0, the base of the address space. And this is the default. Some
553 platforms choose to setup their RAM at other addresses within the
554 processor address space.
557 hex "Size of RAM (in bytes)"
560 Define the size of the system RAM. If you select 0 then the
561 kernel will try to probe the RAM size at runtime. This is not
562 supported on all CPU types.
565 hex "Address of the base of system vectors"
568 Define the address of the system vectors. Commonly this is
569 put at the start of RAM, but it doesn't have to be. On ColdFire
570 platforms this address is programmed into the VBR register, thus
571 actually setting the address to use.
574 hex "Address of the base of kernel code"
577 Typically on m68k systems the kernel will not start at the base
578 of RAM, but usually some small offset from it. Define the start
579 address of the kernel here. The most common setup will have the
580 processor vectors at the base of RAM and then the start of the
581 kernel. On some platforms some RAM is reserved for boot loaders
582 and the kernel starts after that. The 0x400 default was based on
583 a system with the RAM based at address 0, and leaving enough room
584 for the theoretical maximum number of 256 vectors.
587 prompt "RAM bus width"
593 Select the physical RAM data bus size. Not needed on most platforms,
594 so you can generally choose AUTO.
599 Configure RAM bus to be 8 bits wide.
604 Configure RAM bus to be 16 bits wide.
609 Configure RAM bus to be 32 bits wide.
613 comment "ROM configuration"
616 bool "Specify ROM linker regions"
619 Define a ROM region for the linker script. This creates a kernel
620 that can be stored in flash, with possibly the text, and data
621 regions being copied out to RAM at startup.
624 hex "Address of the base of ROM device"
628 Define the address that the ROM region starts at. Some platforms
629 use this to set their chip select region accordingly for the boot
633 hex "Address of the base of the ROM vectors"
637 This is almost always the same as the base of the ROM. Since on all
638 68000 type variants the vectors are at the base of the boot device
642 hex "Size of ROM vector region (in bytes)"
646 Define the size of the vector region in ROM. For most 68000
647 variants this would be 0x400 bytes in size. Set to 0 if you do
648 not want a vector region at the start of the ROM.
651 hex "Address of the base of system image in ROM"
655 Define the start address of the system image in ROM. Commonly this
656 is strait after the ROM vectors.
659 hex "Size of the ROM device"
663 Size of the ROM device. On some platforms this is used to setup
664 the chip select that controls the boot ROM device.
667 prompt "Kernel executes from"
669 Choose the memory type that the kernel will be running in.
674 The kernel will be resident in RAM when running.
679 The kernel will be resident in FLASH/ROM when running. This is
680 often referred to as Execute-in-Place (XIP), since the kernel
681 code executes from the position it is stored in the FLASH/ROM.
