          Linaro toolchain for the ARM architecture. It uses Linaro
          GCC 2014.09 (based on gcc 4.9), Linaro GDB 2013.10 (based on
          GDB 7.6), eglibc 2.19, Binutils 2014.09 (based on 2.24). 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.

          unit to work properly. This unit is available on most
