The purpose of this patch set is to allow the sifive_e machine to run with different CPU targets to enable different ISA entensions. To that end it also introduces a new sifive-e34 CPU type which provides the same ISA as sifive-e31, with the addition of the single precision floating-point extension (f). The default CPU for the sifive_e machine is unchanged.
A user can change the default CPU type by specifying it with the '-cpu' option on the command line.
