Subject: [PATCH v3 25/33] docs: Debugging390.txt: convert table to ascii artwork
Date: Sat, 8 Jun 2019 23:27:15 -0300 [thread overview]
Message-ID: <5673b6b277b851bddfc8eb264aff489e89c9fc9d.1560045490.git.mchehab+samsung@kernel.org> (raw)
In-Reply-To: <cover.1560045490.git.mchehab+samsung@kernel.org>
The first bit/value table inside the document is very
hard to read and won't fit ReST format. Also, some columns aren't
properly aligned.
Convert it to a nice ascii artwork table with makes it easier to
read as plain text and is compatible with ReST format parser
on Sphinx.
