* Change how package pin IO sites are selected.Keith Rothman2021-02-171-1/+17
| | | | | | | The first site type that matches is now selected, under the premise that the early site types are more general. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>
* Continue fixes.Keith Rothman2021-02-171-0/+12

* Add initial site router.Keith Rothman2021-02-171-1/+1
| | | | | | | | This site router likely cannot handle the full problem space. It may need to be replaced with a more generalize approach as testing continues. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>
