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

467 bool "Allow allocating large blocks (> 1MB) of memory"
469 Allow the slab memory allocator to keep chains for very large
470 memory sizes - upto 32MB. You may need this if your system has
471 a lot of RAM, and you need to able to allocate very large
472 contiguous chunks. If unsure, say N.
475 bool "Use 4Kb for kernel stacks instead of 8Kb"
478 If you say Y here the kernel will use a 4Kb stacksize for the
479 kernel stack attached to each process/thread. This facilitates
480 running more threads on a system and also reduces the pressure
481 on the VM subsystem for higher order allocations.
483 comment "RAM configuration"
486 hex "Address of the base of RAM"
489 Define the address that RAM starts at. On many platforms this is
490 0, the base of the address space. And this is the default. Some
491 platforms choose to setup their RAM at other addresses within the
492 processor address space.
495 hex "Size of RAM (in bytes)"
498 Define the size of the system RAM. If you select 0 then the
499 kernel will try to probe the RAM size at runtime. This is not
500 supported on all CPU types.
503 hex "Address of the base of system vectors"
506 Define the address of the system vectors. Commonly this is
507 put at the start of RAM, but it doesn't have to be. On ColdFire
508 platforms this address is programmed into the VBR register, thus
509 actually setting the address to use.
512 hex "Address of the base of kernel code"
515 Typically on m68k systems the kernel will not start at the base
516 of RAM, but usually some small offset from it. Define the start
517 address of the kernel here. The most common setup will have the
518 processor vectors at the base of RAM and then the start of the
519 kernel. On some platforms some RAM is reserved for boot loaders
520 and the kernel starts after that. The 0x400 default was based on
521 a system with the RAM based at address 0, and leaving enough room
522 for the theoretical maximum number of 256 vectors.
525 prompt "RAM bus width"
531 Select the physical RAM data bus size. Not needed on most platforms,
532 so you can generally choose AUTO.
537 Configure RAM bus to be 8 bits wide.
542 Configure RAM bus to be 16 bits wide.
547 Configure RAM bus to be 32 bits wide.
551 comment "ROM configuration"
554 bool "Specify ROM linker regions"
557 Define a ROM region for the linker script. This creates a kernel
558 that can be stored in flash, with possibly the text, and data
559 regions being copied out to RAM at startup.
562 hex "Address of the base of ROM device"
566 Define the address that the ROM region starts at. Some platforms
567 use this to set their chip select region accordingly for the boot
571 hex "Address of the base of the ROM vectors"
575 This is almost always the same as the base of the ROM. Since on all
576 68000 type variants the vectors are at the base of the boot device
580 hex "Size of ROM vector region (in bytes)"
584 Define the size of the vector region in ROM. For most 68000
585 variants this would be 0x400 bytes in size. Set to 0 if you do
586 not want a vector region at the start of the ROM.
589 hex "Address of the base of system image in ROM"
593 Define the start address of the system image in ROM. Commonly this
594 is strait after the ROM vectors.
597 hex "Size of the ROM device"
601 Size of the ROM device. On some platforms this is used to setup
602 the chip select that controls the boot ROM device.
605 prompt "Kernel executes from"
607 Choose the memory type that the kernel will be running in.
612 The kernel will be resident in RAM when running.
617 The kernel will be resident in FLASH/ROM when running. This is
618 often referred to as Execute-in-Place (XIP), since the kernel
619 code executes from the position it is stored in the FLASH/ROM.
