[U-Boot] [PATCH v5 22/27] cmd: mtdparts: accept spi-nand devices

From: Miquel Raynal <miquel.raynal@bootlin.com>
To: u-boot@lists.denx.de
Subject: [U-Boot] [PATCH v5 22/27] cmd: mtdparts: accept spi-nand devices
Date: Mon, 30 Jul 2018 17:46:52 +0200	[thread overview]
Message-ID: <20180730154657.20738-23-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20180730154657.20738-1-miquel.raynal@bootlin.com>

Let spi-nand devices be recognized by mtdparts. This is superfluous
but a full mtdparts rework would be very time-consuming.
