Sorry, I know that doesn't help. So let's walk through my workflow.
I am
not using any Altera tools when I build.
$make socfpga_de0_nano_soc_defconfig
$make u-boot-with-spl.sfp
$dd if=u-boot-with-spl.sfp of=/dev/sdb3
My gcc is: arm-linux-gnueabi-gcc (Ubuntu/Linaro 4.7.3-12ubuntu1)
4.7.3
Has the board ever worked for you at all? Can you try this image:

I just ported U-Boot to another customer board. I noticed QSPI has
problems and USB can be flaky. That's the standard cache issue we
have, disabling dcache fixed that.
I am starting to wonder whether we're hitting some corner case here.
Maybe we should eventually try and trace all the register reads and
writes generated by the DDR calibration code both in old and new SPL
and make a diff to see if something really did change.
Dinh, can you share the marking on the SoC and the DRAMs on your
board?
My SoC is:
5CSEMA4U23C6N
CACAU1525A
DRAMs are:
ISSI 1510
IS43TR16256A
15HBL K080
P4482100QER2 TWN
Thanks, that's indeed rev. C . About time I bang my head against the
desk because this is creepy.
FYI
I've just spend some time trying to update the spl / uboot / kernel &
rootfs image on our
Altera socdk to use for some software testing / development.
Unfortunately it fails in the mem calibration process with the latest
uboot most of the time.
And when it does boot somtimes fails loading uboot fomr the mmc.
Try this u-boot-socfpga/ddr branch [1] , see if it works for you.

Spent a bit of time on it and things are very weird. So far no luck
booting with the ddr branch.
I got the memory calibration to pass but then had problems with loading
uboot. Using the mmc.
Say no device found for the mmc. error -19.
Which board is this ? How wide is the MMC data bus ?
When I try to add some extra debug in things fall over.
Sometimes just hangs in the Memory cal (and not changing anything there).
Then sometimes I get missing DTB.
I found the uboot-with-spl.sfp file generated by the latest uboot tree
and tried burning that with
same results.
Reverted back to the image available on rocketboards and wrote that to
the card.
Thinking something strange with the card (thou I tried several) and that
works fine.

Are you actually using the SoCDK or some custom board ?
I've got two boards here.
The Altera Cyclone V SoC FPGA Development Kit Board RevC
which is the SocDK right?
And our own board design.
Our design works fine with new uboot's.
Just can't get things to work with the dek kit.
It's fairly similar to the SocDK
I'm building two different version of uboot.
Using the two different qts generated files.
I've setup a separate defconfig / dts and board config for our board.
I'd really like to find the quartus project that was used to generate
the qts files committed into the uboot tree. All the ones I've used so
far have different ddr timing and pin configs!
