Subject: [flasher PATCH] Set bootdelay to 0
Date: Wed, 26 Nov 2014 17:57:06 +0000	[thread overview]
Message-ID: <1417024626-6616-2-git-send-email-james.thomas@codethink.co.uk> (raw)
In-Reply-To: <1417024626-6616-1-git-send-email-james.thomas-4yDnlxn2s6sWdaTGBSpHTA@public.gmane.org>

On 32-bit systems fdtput writes 0xfffffffe as 0x7fffffff, which takes
some time to complete.

Setting this to 0 accomplishes the same goal
