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

517 bool "Use 4Kb for kernel stacks instead of 8Kb"
520 If you say Y here the kernel will use a 4Kb stacksize for the
521 kernel stack attached to each process/thread. This facilitates
522 running more threads on a system and also reduces the pressure
523 on the VM subsystem for higher order allocations.
525 comment "RAM configuration"
528 hex "Address of the base of RAM"
531 Define the address that RAM starts at. On many platforms this is
532 0, the base of the address space. And this is the default. Some
533 platforms choose to setup their RAM at other addresses within the
534 processor address space.
537 hex "Size of RAM (in bytes)"
540 Define the size of the system RAM. If you select 0 then the
541 kernel will try to probe the RAM size at runtime. This is not
542 supported on all CPU types.
545 hex "Address of the base of system vectors"
548 Define the address of the system vectors. Commonly this is
549 put at the start of RAM, but it doesn't have to be. On ColdFire
550 platforms this address is programmed into the VBR register, thus
551 actually setting the address to use.
554 hex "Address of the base of kernel code"
557 Typically on m68k systems the kernel will not start at the base
558 of RAM, but usually some small offset from it. Define the start
559 address of the kernel here. The most common setup will have the
560 processor vectors at the base of RAM and then the start of the
561 kernel. On some platforms some RAM is reserved for boot loaders
562 and the kernel starts after that. The 0x400 default was based on
563 a system with the RAM based at address 0, and leaving enough room
564 for the theoretical maximum number of 256 vectors.
567 prompt "RAM bus width"
573 Select the physical RAM data bus size. Not needed on most platforms,
574 so you can generally choose AUTO.
579 Configure RAM bus to be 8 bits wide.
584 Configure RAM bus to be 16 bits wide.
589 Configure RAM bus to be 32 bits wide.
593 comment "ROM configuration"
596 bool "Specify ROM linker regions"
599 Define a ROM region for the linker script. This creates a kernel
600 that can be stored in flash, with possibly the text, and data
601 regions being copied out to RAM at startup.
604 hex "Address of the base of ROM device"
608 Define the address that the ROM region starts at. Some platforms
609 use this to set their chip select region accordingly for the boot
613 hex "Address of the base of the ROM vectors"
617 This is almost always the same as the base of the ROM. Since on all
618 68000 type variants the vectors are at the base of the boot device
622 hex "Size of ROM vector region (in bytes)"
626 Define the size of the vector region in ROM. For most 68000
627 variants this would be 0x400 bytes in size. Set to 0 if you do
628 not want a vector region at the start of the ROM.
631 hex "Address of the base of system image in ROM"
635 Define the start address of the system image in ROM. Commonly this
636 is strait after the ROM vectors.
639 hex "Size of the ROM device"
643 Size of the ROM device. On some platforms this is used to setup
644 the chip select that controls the boot ROM device.
647 prompt "Kernel executes from"
649 Choose the memory type that the kernel will be running in.
654 The kernel will be resident in RAM when running.
659 The kernel will be resident in FLASH/ROM when running. This is
660 often referred to as Execute-in-Place (XIP), since the kernel
661 code executes from the position it is stored in the FLASH/ROM.
