Subject: [U-Boot] [PATCH 1/6] NAND: davinci: add support for NAND chips with 16 bits bus
Date: Tue, 29 Nov 2016 14:31:29 +0100 [thread overview]
Message-ID: <20161129133134.19415-2-fparent@baylibre.com> (raw)
In-Reply-To: <20161129133134.19415-1-fparent@baylibre.com>
The OMAPL138-LCD board uses a NAND chip with a 16 bits bus. Add
support into the davinci driver for 16 bit bus NAND chips.
