111 Support for the Comet platform.
119 string "Default kernel command string"
122 On some platforms, there is currently no way for the boot loader
123 to pass arguments to the kernel. For these, you should supply some
124 command-line options at build time by entering them here. At a
125 minimum, you should specify the memory size and the root device
126 (e.g., mem=64M root=/dev/nfs).
128 config HEXAGON_ANGEL_TRAPS
129 bool "Use Angel Traps"
132 Enable angel debug traps (for printk's).
135 bool "Multi-Processing support"
137 Enables SMP support in the kernel. If unsure, say "Y"
140 int "Maximum number of CPUs" if SMP
145 This allows you to specify the maximum number of CPUs which this
146 kernel will support. The maximum supported value is 6 and the
147 minimum value which makes sense is 2.
149 This is purely to save memory - each supported CPU adds
150 approximately eight kilobytes to the kernel image.

156 Changes the default page size; use with caution.
