I get this in the T4 branch of U-Boot:

It does not appear to be a false positive (though it is an error path), and in any case such warnings should be squashed so that real warnings stick out.
It was introduced by this patch:
commit 18496c6d6cf46177e7faeb364cfe5baddb8cf71e Author: York Sun yorksun@freescale.com Date: Tue Dec 13 14:16:55 2011 -0800
powerpc/mpc8xxx: Add support for cas latency 12 and above Required by JEDEC 79-3E for high speed DDR3. Also change "CSn disabled" message to debug. Signed-off-by: York Sun <yorksun@freescale.com>I also don't see the T4 patches being posted to the mailing list -- why?
And why is there any notion of a 32-bit physical address map for T4, and a README that suggests the 32-bit address map is used?
Please ignore this, I sent it to the wrong mailing list by mistake.
