+        help
+          The C6X function call instruction has a limited range of +/- 2MiB.
+          This is sufficient for most kernels, but some kernel configurations
+          with lots of compiled-in functionality may require a larger range
+          for function calls. Use this option to have the compiler generate
+          function calls with 32-bit range. This will make the kernel both
+          larger and slower.
+
+          If unsure, say N.

+          On some architectures there is currently no way for the boot loader
+          to pass arguments to the kernel. For these architectures, you should
+          supply some command-line options at build time by entering them
+          here.

+config CPU_BIG_ENDIAN
+        bool "Build big-endian kernel"
+        default n
+        help
+          Say Y if you plan on running a kernel in big-endian mode.
+          Note that your board must be properly built and your board
+          port must properly enable any big-endian related features
+          of your chipset/board/processor.
+
+config FORCE_MAX_ZONEORDER
+        int "Maximum zone order"
+        default "13"
+        help
+          The kernel memory allocator divides physically contiguous memory
+          blocks into "zones", where each zone is a power of two number of
+          pages.  This option selects the largest power of two that the kernel
+          keeps in the memory allocator.  If you need to allocate very large
+          blocks of physically contiguous memory, then you may need to
+          increase this value.
+
+          This config option is actually maximum order plus one. For example,
+          a value of 11 means that the largest free memory block is 2^10 pages.
