Anton Blanchard	03fd06deaf	Rework SOC reset ... The old reset code was overly complicated and never worked properly. Replace it with a simpler sequence that uses a couple of shift registers to assert resets: - Wait a number of external clock cycles before removing reset from the PLL. - After the PLL locks and the external reset button isn't pressed, wait a number of PLL clock cycles before removing reset from the SOC.

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.
