+	help
+	  If processor has no CP15 register, this processor ID is
+	  used instead of the auto-probing which utilizes the register.
+
+config REMAP_VECTORS_TO_RAM
+	bool 'Install vectors to the beginning of RAM'
+	help
+	  The kernel needs to change the hardware exception vectors.
+	  In nommu mode, the hardware exception vectors are normally
+	  placed at address 0x00000000. However, this region may be
+	  occupied by read-only memory depending on H/W design.
+
+	  If the region contains read-write memory, say 'n' here.
+
+	  If your CPU provides a remap facility which allows the exception
+	  vectors to be mapped to writable memory, say 'n' here.
+
+	  Otherwise, say 'y' here.  In this case, the kernel will require
+	  external support to redirect the hardware exception vectors to
+	  the writable versions located at DRAM_BASE.
+
+config ARM_MPU
+       bool 'Use the ARM v7 PMSA Compliant MPU'
+       depends on CPU_V7 || CPU_V7M
+       default y if CPU_V7
+       help
+         Some ARM systems without an MMU have instead a Memory Protection
+         Unit (MPU) that defines the type and permissions for regions of
+         memory.
+
+         If your CPU has an MPU then you should choose 'y' here unless you
+         know that you do not want to use the MPU.
