Seems like F484 is the package? Or does that not work for some reason?

No, that should work. I just wasn't entirely sure how the SKU should be split up, but I can fix that and create another pull request if there is nothing else to be addressed (or alternatively push a commit that fixes this).

Adds rudimentary support for the Arrow DECA board (see also the user manual) including the clocks, LEDs, switches, buttons and GPIO connectors as well as setitng the correct voltages for the I/O banks. The board features the Intel Altera MAX10 (10M50DAF484C6GES) FPGA.
There are more peripherals like the ADV7513 for HDMI TX, the TI TLV320AIC3254 24-bit audio codec, an SD card reader, etc. but this commit does not add support for those due to the varying voltages required for the different pins in a lot of cases. In addition, I would like to test any further additions thoroughly before committing them :).
To set the I/O bank voltages correctly, and to make sure Quartus doesn't complain (see also Tom Verbeure's blog post), we have to specify some additional
set_global_assignmentdirectives to the QSF file by overriding thefile_templates()method.I tested the board successfully with Blinky.
Note: I moved this to its own branch, so I can have multiple pull requests. Sorry for the inconvenience.
