unfortunately this is a multi-purpose commit.

unfortunately this is a multi-purpose commit.

it:

1) adds some types AND
2) adds some classes AND
3) fixes some whitespace issues AND
4) (finally) fixes some bugs

we strictly require *single* purpose commits
https://libre-soc.org/HDL_workflow/

Keep commits single-purpose

    edit files making minimal single purpose modifications
    (even if it involves multiple files. Good extreme example:
    globally changing a function name across an entire codebase
    is one purpose, one commit, yet hundreds of files.
    miss out one of those files, requiring multiple commits,
    and it actually becomes a nuisance).
