Subject: [PATCH 2/2] complete: Add completion for nv and globalvar commands
Date: Wed, 19 Oct 2016 08:39:21 +0200	[thread overview]
Message-ID: <20161019063921.13247-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20161019063921.13247-1-s.hauer@pengutronix.de>

The 'nv' command is often used to create a nv variable
for an existing global variable, so add a command completion
function for this.
