Subject: [U-Boot] [PATCH 01/13] mpc8540eval: Split initdram() into initdram() and sdram_init()
Date: Thu,  2 Dec 2010 17:45:27 -0600	[thread overview]
Message-ID: <1291333539-11884-2-git-send-email-beckyb@kernel.crashing.org> (raw)
In-Reply-To: <1291333539-11884-1-git-send-email-beckyb@kernel.crashing.org>

Modeled after the MPC8540DS code; this will allow us to use a common
initdram() once that is available.  There should be no functional
change.
