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

471 bool "Allow allocating large blocks (> 1MB) of memory"
473 Allow the slab memory allocator to keep chains for very large
474 memory sizes - upto 32MB. You may need this if your system has
475 a lot of RAM, and you need to able to allocate very large
476 contiguous chunks. If unsure, say N.
479 bool "Use 4Kb for kernel stacks instead of 8Kb"
482 If you say Y here the kernel will use a 4Kb stacksize for the
483 kernel stack attached to each process/thread. This facilitates
484 running more threads on a system and also reduces the pressure
485 on the VM subsystem for higher order allocations.
487 comment "RAM configuration"
490 hex "Address of the base of RAM"
493 Define the address that RAM starts at. On many platforms this is
494 0, the base of the address space. And this is the default. Some
495 platforms choose to setup their RAM at other addresses within the
496 processor address space.
499 hex "Size of RAM (in bytes)"
502 Define the size of the system RAM. If you select 0 then the
503 kernel will try to probe the RAM size at runtime. This is not
504 supported on all CPU types.
507 hex "Address of the base of system vectors"
510 Define the address of the system vectors. Commonly this is
511 put at the start of RAM, but it doesn't have to be. On ColdFire
512 platforms this address is programmed into the VBR register, thus
513 actually setting the address to use.
516 hex "Address of the base of kernel code"
519 Typically on m68k systems the kernel will not start at the base
520 of RAM, but usually some small offset from it. Define the start
521 address of the kernel here. The most common setup will have the
522 processor vectors at the base of RAM and then the start of the
523 kernel. On some platforms some RAM is reserved for boot loaders
524 and the kernel starts after that. The 0x400 default was based on
525 a system with the RAM based at address 0, and leaving enough room
526 for the theoretical maximum number of 256 vectors.
529 prompt "RAM bus width"
535 Select the physical RAM data bus size. Not needed on most platforms,
536 so you can generally choose AUTO.
541 Configure RAM bus to be 8 bits wide.
546 Configure RAM bus to be 16 bits wide.
551 Configure RAM bus to be 32 bits wide.
555 comment "ROM configuration"
558 bool "Specify ROM linker regions"
561 Define a ROM region for the linker script. This creates a kernel
562 that can be stored in flash, with possibly the text, and data
563 regions being copied out to RAM at startup.
566 hex "Address of the base of ROM device"
570 Define the address that the ROM region starts at. Some platforms
571 use this to set their chip select region accordingly for the boot
575 hex "Address of the base of the ROM vectors"
579 This is almost always the same as the base of the ROM. Since on all
580 68000 type variants the vectors are at the base of the boot device
584 hex "Size of ROM vector region (in bytes)"
588 Define the size of the vector region in ROM. For most 68000
589 variants this would be 0x400 bytes in size. Set to 0 if you do
590 not want a vector region at the start of the ROM.
593 hex "Address of the base of system image in ROM"
597 Define the start address of the system image in ROM. Commonly this
598 is strait after the ROM vectors.
601 hex "Size of the ROM device"
605 Size of the ROM device. On some platforms this is used to setup
606 the chip select that controls the boot ROM device.
609 prompt "Kernel executes from"
611 Choose the memory type that the kernel will be running in.
616 The kernel will be resident in RAM when running.
621 The kernel will be resident in FLASH/ROM when running. This is
622 often referred to as Execute-in-Place (XIP), since the kernel
623 code executes from the position it is stored in the FLASH/ROM.
