Subject: [PATCH 02/11] memory: atmel-ebi: add generic name for ebi regmap
Date: Wed, 13 Feb 2019 08:59:48 +0000 [thread overview]
Message-ID: <20190213085930.31578-3-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20190213085930.31578-1-tudor.ambarus@microchip.com>
From: Tudor Ambarus <tudor.ambarus@microchip.com>
The sam9x60 board defines the CCFG_EBICSA register under SFR,
and not as a MATRIX register, as previous boards do. Add a
more generic name for the EBI regmap as a prerequisite for
sam9x60 ebi support.
