ARC: Add support for nSIM OSCI System C model
This adds support for an ARC Virtual Platform. This platform is based on the System C standard promoted by the OSCI (Open System C Initiative) and uses nSIM to simulate the ARC CPU core itself. Users can build a virtual SoC by combining System C models of peripherals and CPU cores. Signed-off-by: Mischa Jonker <mjonker@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
