There was a problem hiding this comment.
Looks good to me.
This may break some application that assumed the previous incorrect behavior, but it is certainly an improvement over what we had previously.
We might want to do something similar for ReadByte: at the moment it does not block while the vast majority of applications need a blocking interface.

One of the jobs failed- maybe a flaky build? @deadprogram @aykevl |

Resolves #3537, closes #3538.
Adds:
UART.flush: method implemented by UARTs that blocks until all data has finished being transmitteduart.writeByte: method implemented by UARTs that writes over the UART pin without blocking.Semantic changes:
UART.WriteByteandUART.Write: Methods now expected to block until all data has been finished being transmitted over wire.
