45 Qualcomm Hexagon is a processor architecture designed for high
46 performance and low power across a wide variety of applications.
48 config HEXAGON_PHYS_OFFSET
51 Platforms that don't load the kernel at zero set this.
53 config LOCKDEP_SUPPORT
65 config GENERIC_HWEIGHT
68 config STACKTRACE_SUPPORT
76 menu "Machine selection"
85 Support for the Comet platform.

90 int "Architecture version"
94 string "Default kernel command string"
97 On some platforms, there is currently no way for the boot loader
98 to pass arguments to the kernel. For these, you should supply some
99 command-line options at build time by entering them here. At a
100 minimum, you should specify the memory size and the root device
101 (e.g., mem=64M root=/dev/nfs).
104 bool "Multi-Processing support"
106 Enables SMP support in the kernel. If unsure, say "Y"
109 int "Maximum number of CPUs" if SMP
114 This allows you to specify the maximum number of CPUs which this
115 kernel will support. The maximum supported value is 6 and the
116 minimum value which makes sense is 2.
118 This is purely to save memory - each supported CPU adds
119 approximately eight kilobytes to the kernel image.
