From b67996c48f1bc91412605acd7012f242514d3927 Mon Sep 17 00:00:00 2001

Subject: Add smoke tests for a selection of iCE40, ECP5, Xilinx, Intel boards.

The purpose of these tests is just to ensure that Amaranth changes do
not blatantly break the boards repository. They are not intended to
exhaustively test even a single board.

Everything Gowin-related is removed due to Apicula's problematic use
of numpy.
