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

545 If you say Y here the kernel will use a 4Kb stacksize for the
546 kernel stack attached to each process/thread. This facilitates
547 running more threads on a system and also reduces the pressure
548 on the VM subsystem for higher order allocations.

555 comment "RAM configuration"
558 hex "Address of the base of RAM"
561 Define the address that RAM starts at. On many platforms this is
562 0, the base of the address space. And this is the default. Some
563 platforms choose to setup their RAM at other addresses within the
564 processor address space.
567 hex "Size of RAM (in bytes), or 0 for automatic"
570 Define the size of the system RAM. If you select 0 then the
571 kernel will try to probe the RAM size at runtime. This is not
572 supported on all CPU types.
575 hex "Address of the base of system vectors"
578 Define the address of the system vectors. Commonly this is
579 put at the start of RAM, but it doesn't have to be. On ColdFire
580 platforms this address is programmed into the VBR register, thus
581 actually setting the address to use.
584 hex "Address of the base of kernel code"
587 Typically on m68k systems the kernel will not start at the base
588 of RAM, but usually some small offset from it. Define the start
589 address of the kernel here. The most common setup will have the
590 processor vectors at the base of RAM and then the start of the
591 kernel. On some platforms some RAM is reserved for boot loaders
592 and the kernel starts after that. The 0x400 default was based on
593 a system with the RAM based at address 0, and leaving enough room
594 for the theoretical maximum number of 256 vectors.
597 prompt "RAM bus width"
603 Select the physical RAM data bus size. Not needed on most platforms,
604 so you can generally choose AUTO.
609 Configure RAM bus to be 8 bits wide.
614 Configure RAM bus to be 16 bits wide.
619 Configure RAM bus to be 32 bits wide.
623 comment "ROM configuration"
626 bool "Specify ROM linker regions"
629 Define a ROM region for the linker script. This creates a kernel
630 that can be stored in flash, with possibly the text, and data
631 regions being copied out to RAM at startup.
634 hex "Address of the base of ROM device"
638 Define the address that the ROM region starts at. Some platforms
639 use this to set their chip select region accordingly for the boot
643 hex "Address of the base of the ROM vectors"
647 This is almost always the same as the base of the ROM. Since on all
648 68000 type variants the vectors are at the base of the boot device
652 hex "Size of ROM vector region (in bytes)"
656 Define the size of the vector region in ROM. For most 68000
657 variants this would be 0x400 bytes in size. Set to 0 if you do
658 not want a vector region at the start of the ROM.
661 hex "Address of the base of system image in ROM"
665 Define the start address of the system image in ROM. Commonly this
666 is strait after the ROM vectors.
669 hex "Size of the ROM device"
673 Size of the ROM device. On some platforms this is used to setup
674 the chip select that controls the boot ROM device.
677 prompt "Kernel executes from"
679 Choose the memory type that the kernel will be running in.
684 The kernel will be resident in RAM when running.
689 The kernel will be resident in FLASH/ROM when running. This is
690 often referred to as Execute-in-Place (XIP), since the kernel
691 code executes from the position it is stored in the FLASH/ROM.
