+config PREEMPT
+	bool "Preemptible Kernel"
+	help
+	  This option reduces the latency of the kernel when reacting to
+	  real-time or interactive events by allowing a low priority process to
+	  be preempted even if it is in kernel mode executing a system call.
+	  This allows applications to run more reliably even when the system is
+	  under load.
+
+	  Say Y here if you are building a kernel for a desktop, embedded
+	  or real-time system.  Say N if you are unsure.
+
+config PREEMPT_TIMES
+	bool "Collect preemption latency times"
+	depends on PREEMPT
+	help
+	  Allow collection for preemption latency times.

+    depends on MICROBLAZE
+    default y
+    help
+      This is needed to be able to allocate uncachable memory regions.
+      The feature requires the design to define the RAM memory controller window
+      to be twice as large as the actual physical memory.
+
+config LARGE_ALLOCS
+       bool "Allow allocating large blocks (> 1MB) of memory"
+       help
+            Allow the slab memory allocator to keep chains for very large
+            memory sizes - upto 32MB. You may need this if your system has
+            a lot of RAM, and you need to able to allocate very large
+            contiguous chunks. If unsure, say N.

+
+config CMDLINE
+	string "Default kernel command string"
+	default ""
+	help
+	  On some architectures there is currently no way for the boot loader
+	  to pass arguments to the kernel. For these architectures, you should
