Subject: [RFC PATCH 03/14] ARM: OMAP1: ams-delta: Provide board specific partition info
Date: Wed, 12 Feb 2020 01:39:18 +0100 [thread overview]
Message-ID: <20200212003929.6682-4-jmkrzyszt@gmail.com> (raw)
In-Reply-To: <20200212003929.6682-1-jmkrzyszt@gmail.com>
Now as the Amstrad Delta NAND driver supports fetching information on
MTD partitions from device platform data, add partition info to the
NAND device configuration.
