Subject: [PATCH v2 8/9] mtd: rawnand: jedec: Define the number of parameter pages
Date: Fri, 24 Apr 2020 18:40:41 +0200	[thread overview]
Message-ID: <20200424164042.26572-9-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20200424164042.26572-1-miquel.raynal@bootlin.com>

Use a macro to define the number of parameter page instead of
hardcoding it everywhere.
