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

459 bool "Allow allocating large blocks (> 1MB) of memory"
461 Allow the slab memory allocator to keep chains for very large
462 memory sizes - upto 32MB. You may need this if your system has
463 a lot of RAM, and you need to able to allocate very large
464 contiguous chunks. If unsure, say N.
467 bool "Use 4Kb for kernel stacks instead of 8Kb"
470 If you say Y here the kernel will use a 4Kb stacksize for the
471 kernel stack attached to each process/thread. This facilitates
472 running more threads on a system and also reduces the pressure
473 on the VM subsystem for higher order allocations.
475 comment "RAM configuration"
478 hex "Address of the base of RAM"
481 Define the address that RAM starts at. On many platforms this is
482 0, the base of the address space. And this is the default. Some
483 platforms choose to setup their RAM at other addresses within the
484 processor address space.
487 hex "Size of RAM (in bytes)"
490 Define the size of the system RAM. If you select 0 then the
491 kernel will try to probe the RAM size at runtime. This is not
492 supported on all CPU types.
495 hex "Address of the base of system vectors"
498 Define the address of the system vectors. Commonly this is
499 put at the start of RAM, but it doesn't have to be. On ColdFire
500 platforms this address is programmed into the VBR register, thus
501 actually setting the address to use.
504 hex "Address of the base of kernel code"
507 Typically on m68k systems the kernel will not start at the base
508 of RAM, but usually some small offset from it. Define the start
509 address of the kernel here. The most common setup will have the
510 processor vectors at the base of RAM and then the start of the
511 kernel. On some platforms some RAM is reserved for boot loaders
512 and the kernel starts after that. The 0x400 default was based on
513 a system with the RAM based at address 0, and leaving enough room
514 for the theoretical maximum number of 256 vectors.
517 prompt "RAM bus width"
523 Select the physical RAM data bus size. Not needed on most platforms,
524 so you can generally choose AUTO.
529 Configure RAM bus to be 8 bits wide.
534 Configure RAM bus to be 16 bits wide.
539 Configure RAM bus to be 32 bits wide.
543 comment "ROM configuration"
546 bool "Specify ROM linker regions"
549 Define a ROM region for the linker script. This creates a kernel
550 that can be stored in flash, with possibly the text, and data
551 regions being copied out to RAM at startup.
554 hex "Address of the base of ROM device"
558 Define the address that the ROM region starts at. Some platforms
559 use this to set their chip select region accordingly for the boot
563 hex "Address of the base of the ROM vectors"
567 This is almost always the same as the base of the ROM. Since on all
568 68000 type variants the vectors are at the base of the boot device
572 hex "Size of ROM vector region (in bytes)"
576 Define the size of the vector region in ROM. For most 68000
577 variants this would be 0x400 bytes in size. Set to 0 if you do
578 not want a vector region at the start of the ROM.
581 hex "Address of the base of system image in ROM"
585 Define the start address of the system image in ROM. Commonly this
586 is strait after the ROM vectors.
589 hex "Size of the ROM device"
593 Size of the ROM device. On some platforms this is used to setup
594 the chip select that controls the boot ROM device.
597 prompt "Kernel executes from"
599 Choose the memory type that the kernel will be running in.
604 The kernel will be resident in RAM when running.
609 The kernel will be resident in FLASH/ROM when running. This is
610 often referred to as Execute-in-Place (XIP), since the kernel
611 code executes from the position it is stored in the FLASH/ROM.
