Now we only support CSKY 800 series cpus and newer cpus in the future undering CSKYv2 ABI specification. There are 11 processor family enums for CK series cpus such as CK801, CK802, CK803, CK803S, CK804, CK805, CK807, CK810, CK810V, CK860, CK860V. The SchedMachineModels are not ready for different cpus, so only NoSchedModel is used.
