Subject: fsl-ddr: ignore memctl_intlv_ctl setting if only one DDR controller
X-Git-Tag: v2009.03-rc1~76
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1542fbdeec0d1e2a6df13189df8dcb1ce8802be3;p=kernel%2Fu-boot.git

fsl-ddr: ignore memctl_intlv_ctl setting if only one DDR controller

If we only have one controller we can completely ignore how
memctl_intlv_ctl is set.  Otherwise other levels of code get confused
and think we have twice as much memory.
