Subject: [U-Boot] [PATCH] IDE: Don't assume there are always two devices per bus
Date: Mon, 16 Aug 2010 07:47:40 +0200 [thread overview]
Message-ID: <1281937660-25632-2-git-send-email-user@aphrodite> (raw)
In-Reply-To: <20100815213046.A427B1606A5@gemini.denx.de>
From: Rogan Dawes <rogan@dawes.za.net>
Some SATA controllers can operate in an IDE compatible mode (e.g. mvsata)
but will only ever have a single device per bus.
This allows the upcoming DNS323 port to properly identify and use
a drive on both SATA interfaces.
