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.
