The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

The underlying serial IP block is relatively basic, and currently does not support serial break detection. Further information on the IP block can be found in the documentation and Chisel sources: https://static.dev.sifive.com/FU540-C000-v1.0.pdf https://github.com/sifive/sifive-blocks/tree/master/src/main/scala/devices/uart This driver was written in collaboration with Wesley Terpstra . Tested on a SiFive HiFive Unleashed A00 board, using BBL and the open- source FSBL (using a DT file based on what's targeted for mainline). This revision incorporates changes based on comments by Julia Lawall , Emil Renner Berthing , and Andreas Schwab . Thanks also to Andreas for testing the driver with his userspace and reporting a bug with the set_termios implementation.
