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

153 default PAGE_SIZE_4KB
155 Changes the default page size; use with caution.
