36 Qualcomm Hexagon is a processor architecture designed for high
37 performance and low power across a wide variety of applications.
39 config HEXAGON_PHYS_OFFSET
42 Platforms that don't load the kernel at zero set this.

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

149 Changes the default page size; use with caution.
