Subject: [U-Boot] [PATCH 3/7] serial: serial_msm: initialize uart only before relocation
Date: Sat, 12 May 2018 13:15:54 +0300 [thread overview]
Message-ID: <20180512101558.24375-4-ramon.fried@gmail.com> (raw)
In-Reply-To: <20180512101558.24375-1-ramon.fried@gmail.com>
The uart is already initialized prior to relocation,
reinitialization after relocation is unnecessary.
