Subject: [PATCH v5 2/8] mtd: spi-nor: Add a macro to define more banks
Date: Tue, 28 Mar 2023 17:40:59 +0200	[thread overview]
Message-ID: <20230328154105.448540-3-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20230328154105.448540-1-miquel.raynal@bootlin.com>

Most of the chips on the market only feature a single bank. However, new
chips may support more than a single bank, with the possibility to
parallelize some operations. Let's introduce an INFOB() macro which also
takes a n_bank parameter.
