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

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