Subject: [PATCH] mtd: rawnand: gpmi: Introduce GPMI_IS_MXS() macro
Date: Thu,  7 Feb 2019 08:50:54 -0200	[thread overview]
Message-ID: <20190207105055.10860-1-festevam@gmail.com> (raw)

Introduce a GPMI_IS_MXS() macro to take into account the cases
when mx23 or mx28 are used, which helps readability.
