Subject: [U-Boot] [PATCH v4 11/21] sf: Move BAR defined code at once place
Date: Mon, 12 Oct 2015 20:31:04 +0530	[thread overview]
Message-ID: <1444662074-2424-12-git-send-email-jteki@openedev.com> (raw)
In-Reply-To: <1444662074-2424-1-git-send-email-jteki@openedev.com>

Move bar read code below the bar write hance both at once place,
hence it easy for #ifdef macro only once and readable.
