Subject: [PATCH v2] imx-bbu-nand-fcb: fix build on MX28 only
Date: Fri, 17 Nov 2017 19:14:26 +0100	[thread overview]
Message-ID: <20171117181426.27347-1-l.stach@pengutronix.de> (raw)

This code may be compiled without ARCH_IMX6 present, so it must not
depend on any functions provided by the architecture support.

Fixes: a2618c215bff (imx-bbu-nand-fcb: add support for imx6ul)
Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
---
v2: Remove ifdeffery by introducing a dedicated function, as
    suggested by Sascha.
