Anton Blanchard	5e140298a5	Rework decode2 The decode2 stage was spaghetti code and needed cleaning up. Create a series of functions to pull fields from a ppc instruction and also a series of helpers to extract values for the execution units. As suggested by Paul, we should pass all signals to the execution units and only set the valid signal conditionally, which should use less resources.

Olof Kindgren	b9bf19f912	Added synthesis target The synth target can be used to analyze the core after synthesis without running P&R. Currently, the only edalize backends that support synthesis without P&R are vivado and icestorm, and icestorm needs yosys built with verific support to parse vhdl. To run synthesis only for a part, run fusesoc run --target=synth --tool=vivado microwatt --part=<part> where part is a valid Xilinx part such as xc7a100tcsg324-1	6 years ago
