Subject: [PATCH 10/14] ARM: Layerscape: TQMLS1046a: print life signs when debugging
Date: Fri, 10 May 2019 08:21:31 +0200 [thread overview]
Message-ID: <20190510062135.11534-11-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20190510062135.11534-1-s.hauer@pengutronix.de>
Do the UART initialization after the SoC specific lowlevel setup and
print the usual '>' when early debuging is enabled. To let this go out
properly it seems we have to wait a small amount of time beforehand.
