+	  Linaro toolchain for the ARM architecture. It uses Linaro
+	  GCC 2012.05 (based on gcc 4.7), Linaro GDB 2012.05 (based on
+	  GDB 7.4), eglibc 2.13. It generates code that runs on all
+	  Cortex-A profile devices, but tuned for the Cortex-A9. The
+	  code generated is Thumb 2, with the hard floating point
+	  calling convention, and uses the VFPv3-D16 FPU instructions.
+
+	  To use this toolchain, you must disable soft float usage.
