34 Qualcomm Hexagon is a processor architecture designed for high
35 performance and low power across a wide variety of applications.

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

150 Changes the default page size; use with caution.
