Subject: [PATCH 1/3] feature-arm-thumb.inc: drop ARM -vs- thumb comments
Date: Tue, 8 Dec 2015 17:09:56 -0800 [thread overview]
Message-ID: <1449623398-29127-2-git-send-email-armccurdy@gmail.com> (raw)
In-Reply-To: <1449623398-29127-1-git-send-email-armccurdy@gmail.com>
Comments are old and specific to thumb1. Since oe-core CPU tuning
files aren't really the right place to fully document ARM -vs- thumb,
drop the comments instead of trying to update them.
