+	  Arm toolchain for the ARM architecture. It uses GCC 8.3.1,
+	  GDB 8.2.1, glibc 2.28, Binutils 2.32. It generates code that
+	  runs on all Cortex-A profile devices, but tuned for the
+	  Cortex-A9. The code generated uses the hard floating point
+	  calling convention, and uses the VFPv3-D16 FPU instructions.
+
+	  This is the same toolchain that was previously distributed by
+	  Linaro.
