This series adds a serial driver, with console support, for the
UART IP block present on the SiFive FU540 SoC.  The programming
model is straightforward, but unique.

Boot-tested on a SiFive FU540 HiFive-U board (with appropriate patches
to the DT data).

The patches in this series can also be found at:


This third version updates the DT binding documentation per discussion
with Rob Herring and fixes one additional issue identified by the 0-day
build system related to MODULE_DEVICE_TABLE.
