Hi!

What's this patch ? Can you share it ?

Can you share this change ?

The rev E1 is the latest SoCDK, I only have rev. C1 . I remember Dinh
(CCed) did send a patch for the rev. E board , so I assume he did test
it, but those were only pinmux changes and it should be part of the
v2016.05:

    arm: socfpga: Update iomux and pll for c5 socdk RevE

Another thing which comes to mind is the change in size of SPL, that
might be worth looking at. Can you check the size of the SPL,
u-boot-spl-dtb.bin ?

I just tested the rev C socdk with 2016.05 and it boots for me. I will
send you the binary I used off-list.

Yesterday I was able to identify a workaround to get the SPL going by disabling quad mode for the flash (seems identified by http://lists.denx.de/pipermail/u-boot/2016-June/256671.html). However u-boot always hangs after printing memory size. I have tried to search the archive and have seen posts about hanging here, but nothing I can relate to my setup. I have tested to use Altera's SPL (2013.01.01) and u-boot-2016.5 and this combo seems to work.
