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

154 Changes the default page size; use with caution.
