Subject: [PATCH 4/4] ARM: tqma53: call SoC lowlevel function early
Date: Wed, 3 Apr 2013 09:09:40 +0200 [thread overview]
Message-ID: <1364972980-32527-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1364972980-32527-1-git-send-email-s.hauer@pengutronix.de>
With CONFIG_MMU_EARLY enabled the board does not survive the call
to imx53_init_lowlevel(). This should not happen, but the reasons
are currently unknown. This works on other boards like the i.MX53
QSB.
This patch moves the call to imx53_init_lowlevel to
barebox_arm_reset_vector() which is executed with MMU disabled.
