Corstone1000 is a platform from arm, which includes pre
verified Corstone SSE710 sub-system that combines Cortex-A and
Cortex-M processors [0].

This code adds the support for the Cortex-A35 implementation
at host side, it contains also the necessary bits to support
the Corstone 1000 FVP (Fixed Virtual Platform) [1] and also the
FPGA MPS3 board implementation of this platform. [2]
