VCC enables the virtualization of serial console on SPARC processors. VCC provides access to the guest domain's serial console. VCC depends on some core functionalities in the linux kernel for SPARC. The functionalities include LDC (Logical Domain Channels), MDESC (Machine Descriptor) and VIO (Virtual IO protocol). In order for VCC to be enabled, it requires that these core functionalities support them. This series of patches adds MDESC & VIO support to enable VCC on Linux. It is the second batch of changes to enable VCC.
