8050e796ab hardware: pcb: clean up traces, widen up pours
Rework the traces somewhat to widen up the pours and remove some of the
bifurcation that's going on.

66584765ff hardware: footprints: add new SON50
This has more copper, which might make hand-soldering easier.  Though
this PCB isn't going to be hand-soldered.

d2b73fbc5e hardware: schematic: rewire fpga as necessary for routing
FPGAs are great, because if there's an alternate method that's easier to
route -- go for it!  This modifies some of the connections to ease
routing constraints.

This is the first cut of a schematic layout of DVT1.

It includes all the decoupling caps still.  We'll need to see if they're

34f74fbf51 hardware: sch: first draft of dvt1
This removes much of the support debugging stuff from evt1.  Still to
do:

- Assign footprints
- Figure out which PU resistor to include (if any)
- Figure out if we need to keep the USB buffering
- Remove extra decoupling caps

0bda71a0c8 hardware: footprints: add power regulator footprint

It refers to a 3D file that doesn't exist, so we'll need to find that

9639d75a11 releases: remove evt1 and evt2, and rename evt3 -> evt1
evt1 and evt2 were never produced.  They also would never have worked,
because the USB connector was drawn mirrored.

Remove these and replace them with a single `evt1` that was actually
produced.

This reflects the fact that the `evt1` boards actually say "EVT1" on
them.

e48d836372 pcb: remove usb silk, add more 5V vias
Add more 5V vias near the 1.2V regulator, and replace a manual trace
with a copper pour.  This will increase the amount of copper going to
both the 3.3V and 1.2V regulators, which should improve stability.

While we're at it, remove an errant silk artifact on the USB connector.
