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

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

543 comment "RAM configuration"
546 hex "Address of the base of RAM"
549 Define the address that RAM starts at. On many platforms this is
550 0, the base of the address space. And this is the default. Some
551 platforms choose to setup their RAM at other addresses within the
552 processor address space.
555 hex "Size of RAM (in bytes)"
558 Define the size of the system RAM. If you select 0 then the
559 kernel will try to probe the RAM size at runtime. This is not
560 supported on all CPU types.
563 hex "Address of the base of system vectors"
566 Define the address of the system vectors. Commonly this is
567 put at the start of RAM, but it doesn't have to be. On ColdFire
568 platforms this address is programmed into the VBR register, thus
569 actually setting the address to use.
572 hex "Address of the base of kernel code"
575 Typically on m68k systems the kernel will not start at the base
576 of RAM, but usually some small offset from it. Define the start
577 address of the kernel here. The most common setup will have the
578 processor vectors at the base of RAM and then the start of the
579 kernel. On some platforms some RAM is reserved for boot loaders
580 and the kernel starts after that. The 0x400 default was based on
581 a system with the RAM based at address 0, and leaving enough room
582 for the theoretical maximum number of 256 vectors.
585 prompt "RAM bus width"
591 Select the physical RAM data bus size. Not needed on most platforms,
592 so you can generally choose AUTO.
597 Configure RAM bus to be 8 bits wide.
602 Configure RAM bus to be 16 bits wide.
607 Configure RAM bus to be 32 bits wide.
611 comment "ROM configuration"
614 bool "Specify ROM linker regions"
617 Define a ROM region for the linker script. This creates a kernel
618 that can be stored in flash, with possibly the text, and data
619 regions being copied out to RAM at startup.
622 hex "Address of the base of ROM device"
626 Define the address that the ROM region starts at. Some platforms
627 use this to set their chip select region accordingly for the boot
631 hex "Address of the base of the ROM vectors"
635 This is almost always the same as the base of the ROM. Since on all
636 68000 type variants the vectors are at the base of the boot device
640 hex "Size of ROM vector region (in bytes)"
644 Define the size of the vector region in ROM. For most 68000
645 variants this would be 0x400 bytes in size. Set to 0 if you do
646 not want a vector region at the start of the ROM.
649 hex "Address of the base of system image in ROM"
653 Define the start address of the system image in ROM. Commonly this
654 is strait after the ROM vectors.
657 hex "Size of the ROM device"
661 Size of the ROM device. On some platforms this is used to setup
662 the chip select that controls the boot ROM device.
665 prompt "Kernel executes from"
667 Choose the memory type that the kernel will be running in.
672 The kernel will be resident in RAM when running.
677 The kernel will be resident in FLASH/ROM when running. This is
678 often referred to as Execute-in-Place (XIP), since the kernel
679 code executes from the position it is stored in the FLASH/ROM.
