Qualcomm Hexagon is a processor architecture designed for high performance and low power across a wide variety of applications.
Platforms that don't load the kernel at zero set this.
Support for the Comet platform.
On some platforms, there is currently no way for the boot loader to pass arguments to the kernel. For these, you should supply some command-line options at build time by entering them here. At a minimum, you should specify the memory size and the root device (e.g., mem=64M root=/dev/nfs).
Enables SMP support in the kernel. If unsure, say "Y"
This allows you to specify the maximum number of CPUs which this kernel will support. The maximum supported value is 6 and the minimum value which makes sense is 2. This is purely to save memory - each supported CPU adds approximately eight kilobytes to the kernel image.
Changes the default page size; use with caution.
