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 gernal the kernel won't setup a PLL
165 if it is fitted (there are some expections). 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 ration 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.
482 Configure the RAM size on your platform. Many platforms can auto
483 detect this, on those choose the AUTO option. Otherwise set the
484 RAM size you intend using.
489 Set RAM size to be 4MiB.
494 Set RAM size to be 8MiB.
499 Set RAM size to be 16MiB.
504 Set RAM size to be 32MiB.
509 prompt "RAM bus width"
515 Select the physical RAM data bus size. Not needed on most platforms,
516 so you can generally choose AUTO.
521 Configure RAM bus to be 8 bits wide.
526 Configure RAM bus to be 16 bits wide.
531 Configure RAM bus to be 32 bits wide.
536 prompt "Kernel executes from"
538 Choose the memory type that the kernel will be running in.
543 The kernel will be resident in RAM when running.
548 The kernel will be resident in FLASH/ROM when running.
