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

474 bool "Allow allocating large blocks (> 1MB) of memory"
476 Allow the slab memory allocator to keep chains for very large
477 memory sizes - upto 32MB. You may need this if your system has
478 a lot of RAM, and you need to able to allocate very large
479 contiguous chunks. If unsure, say N.
482 bool "Use 4Kb for kernel stacks instead of 8Kb"
485 If you say Y here the kernel will use a 4Kb stacksize for the
486 kernel stack attached to each process/thread. This facilitates
487 running more threads on a system and also reduces the pressure
488 on the VM subsystem for higher order allocations.
490 comment "RAM configuration"
493 hex "Address of the base of RAM"
496 Define the address that RAM starts at. On many platforms this is
497 0, the base of the address space. And this is the default. Some
498 platforms choose to setup their RAM at other addresses within the
499 processor address space.
502 hex "Size of RAM (in bytes)"
505 Define the size of the system RAM. If you select 0 then the
506 kernel will try to probe the RAM size at runtime. This is not
507 supported on all CPU types.
510 hex "Address of the base of system vectors"
513 Define the address of the system vectors. Commonly this is
514 put at the start of RAM, but it doesn't have to be. On ColdFire
515 platforms this address is programmed into the VBR register, thus
516 actually setting the address to use.
519 hex "Address of the base of kernel code"
522 Typically on m68k systems the kernel will not start at the base
523 of RAM, but usually some small offset from it. Define the start
524 address of the kernel here. The most common setup will have the
525 processor vectors at the base of RAM and then the start of the
526 kernel. On some platforms some RAM is reserved for boot loaders
527 and the kernel starts after that. The 0x400 default was based on
528 a system with the RAM based at address 0, and leaving enough room
529 for the theoretical maximum number of 256 vectors.
532 prompt "RAM bus width"
538 Select the physical RAM data bus size. Not needed on most platforms,
539 so you can generally choose AUTO.
544 Configure RAM bus to be 8 bits wide.
549 Configure RAM bus to be 16 bits wide.
554 Configure RAM bus to be 32 bits wide.
558 comment "ROM configuration"
561 bool "Specify ROM linker regions"
564 Define a ROM region for the linker script. This creates a kernel
565 that can be stored in flash, with possibly the text, and data
566 regions being copied out to RAM at startup.
569 hex "Address of the base of ROM device"
573 Define the address that the ROM region starts at. Some platforms
574 use this to set their chip select region accordingly for the boot
578 hex "Address of the base of the ROM vectors"
582 This is almost always the same as the base of the ROM. Since on all
583 68000 type variants the vectors are at the base of the boot device
587 hex "Size of ROM vector region (in bytes)"
591 Define the size of the vector region in ROM. For most 68000
592 variants this would be 0x400 bytes in size. Set to 0 if you do
593 not want a vector region at the start of the ROM.
596 hex "Address of the base of system image in ROM"
600 Define the start address of the system image in ROM. Commonly this
601 is strait after the ROM vectors.
604 hex "Size of the ROM device"
608 Size of the ROM device. On some platforms this is used to setup
609 the chip select that controls the boot ROM device.
612 prompt "Kernel executes from"
614 Choose the memory type that the kernel will be running in.
619 The kernel will be resident in RAM when running.
624 The kernel will be resident in FLASH/ROM when running. This is
625 often referred to as Execute-in-Place (XIP), since the kernel
626 code executes from the position it is stored in the FLASH/ROM.
