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

157 Changes the default page size; use with caution.
