Support for the Comet platform.

help

On some platforms， there is currently no way for the boot loader

to pass arguments to the kernel. For these， you should supply some

command-line options at build time by entering them here. At a

minimum， you should specify the memory size and the root device

(e.g.， mem=64M root=/dev/nfs).

config SMP

bool "Multi-Processing support"

---help---

Enables SMP support in the kernel. If unsure， say "Y"

config NR_CPUS

range 2 6 if SMP

default "1" if !SMP

default "6" if SMP

---help---

This allows you to specify the maximum number of CPUs which this

kernel will support. The maximum supported value is 6 and the

minimum value which makes sense is 2.

This is purely to save memory - each supported CPU adds

approximately eight kilobytes to the kernel image.
