Subject: [PATCH] ARM: mvebu: fix size mask for RAM window
Date: Tue, 13 Jun 2017 00:37:49 +0200	[thread overview]
Message-ID: <20170612223749.13780-1-u.kleine-koenig@pengutronix.de> (raw)

The size field in the window control register occupies bits 31:16. So
adapt ARMADA_370_XP_DDR_SIZE_MASK accordingly. This fixes detection of
RAM chips smaller than 32 MiB and so probably doesn't affect any
supported machine.
