Subject: [PATCH 3/4] ARM: start: simplify board_data sdram allocation
Date: Thu, 16 Jun 2016 15:18:21 +0200	[thread overview]
Message-ID: <1466083102-6241-3-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1466083102-6241-1-git-send-email-s.hauer@pengutronix.de>

We already have a pointer for barebox_boarddata, so use it to
request the corresponding SDRAM region instead of calculating
it again.
