Subject: [U-Boot] [PATCH v3 19/21] efi_loader: split out escape sequence based size query
Date: Wed, 13 Sep 2017 18:05:42 -0400 [thread overview]
Message-ID: <20170913220546.19560-20-robdclark@gmail.com> (raw)
In-Reply-To: <20170913220546.19560-1-robdclark@gmail.com>
We need to do something different for vidconsole, since it cannot
respond to the query on stdin. Prep work for next patch.
