Subject: [PATCH 06/12] ARM: i.MX: Provide bootsource functions for early boot code
Date: Wed, 14 Sep 2016 11:12:42 +0200 [thread overview]
Message-ID: <1473844368-13030-6-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1473844368-13030-1-git-send-email-s.hauer@pengutronix.de>
The regular bootsource functions only work in a running barebox,
provide functions for early code. This has already been done for
i.MX6, this patch adds the same functions for the other SoCs.
