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

39 Platforms that don't load the kernel at zero set this.

97 Support for the Comet platform.

102 int "Architecture version"
106 string "Default kernel command string"
109 On some platforms, there is currently no way for the boot loader
110 to pass arguments to the kernel. For these, you should supply some
111 command-line options at build time by entering them here. At a
112 minimum, you should specify the memory size and the root device
113 (e.g., mem=64M root=/dev/nfs).
116 bool "Multi-Processing support"
118 Enables SMP support in the kernel. If unsure, say "Y"
121 int "Maximum number of CPUs" if SMP
126 This allows you to specify the maximum number of CPUs which this
127 kernel will support. The maximum supported value is 6 and the
128 minimum value which makes sense is 2.
130 This is purely to save memory - each supported CPU adds
131 approximately eight kilobytes to the kernel image.
134 prompt "Kernel page size"
135 default PAGE_SIZE_4KB
137 Changes the default page size; use with caution.
