    Here's a bit of work in progress for getting the Zip CPU working on a XuLA2
    board. Many changes include: the existence of a cpudefs.v file to control
    what "options" are included in the ZipCPU build. This allows build control
    to be separated from the project directory (one build for a XuLA2 board,
    another for a Basys-3 development board). Other changes have made things
    perhaps harder to read, but they get rid of warnings from XST.

    A big change was the addition of the (* ram_style="distributed" *) comment
    for the register set. This was necessary to keep XST from inferring a block
    RAM and breaking the logic that was supposed to take place between a register
    read and when it was used.
