Subject: [U-Boot] [PATCH V2 03/12] mpc85xx/tlb.c: Allow platforms to specify wimge bits
Date: Mon, 13 Dec 2010 15:06:43 -0600 [thread overview]
Message-ID: <1292274412-11340-4-git-send-email-beckyb@kernel.crashing.org> (raw)
In-Reply-To: <1292274412-11340-3-git-send-email-beckyb@kernel.crashing.org>
Some platforms might want to override the default wimge=0 for
DDR. Add CONFIG_DDR_TLB_WIMGE for those platforms to use.
This will initially only be used by TQM85xx, but could be
useful for other boards or testing going forward.
