118 Support for the Comet platform.
126 string "Default kernel command string"
129 On some platforms, there is currently no way for the boot loader
130 to pass arguments to the kernel. For these, you should supply some
131 command-line options at build time by entering them here. At a
132 minimum, you should specify the memory size and the root device
133 (e.g., mem=64M root=/dev/nfs).
135 config HEXAGON_ANGEL_TRAPS
136 bool "Use Angel Traps"
139 Enable angel debug traps (for printk's).
142 bool "Multi-Processing support"
144 Enables SMP support in the kernel. If unsure, say "Y"
147 int "Maximum number of CPUs" if SMP
152 This allows you to specify the maximum number of CPUs which this
153 kernel will support. The maximum supported value is 6 and the
154 minimum value which makes sense is 2.
156 This is purely to save memory - each supported CPU adds
157 approximately eight kilobytes to the kernel image.
160 prompt "Kernel page size"
161 default PAGE_SIZE_4KB
163 Changes the default page size; use with caution.
