Glasgow Embedded / Glasgow - History

applet.interface.uart: count and display receive errors.

device.simulation: fix {read,write}_register APIs to match hardware.

applet.interface.uart: perform most baud rate changes at runtime.

The divisor register is intentionally not kept wider than what's
needed for 9600 baud since that would negatively impact Fmax.
Nevertheless if you do request such a low baud rate it is still
supported, just with more bitstream rebuilds.

gateware.uart: allow reconfiguring baud rate at runtime.

If never changed this register will be eliminated by the synthesizer.

gateware.clockgen: more consistent units display in logs. NFC.

revC1: add 1V2 testpoint to the rear

Also fix some testpoint value tags

revC1: add protection resistor to FPGA Sync pin

Closes: #125
Closes: #126

revC: correct the explanation for GBIN0/1 balls being shared.
