This is already a lot better. It means that you get your bootloader
loaded instead of boot0. Now it's only a matter to make it work right.

You get the SPL part successfully loaded by the boot ROM into the SRAM.
Then the SPL tries to load the rest of the U-Boot code into the DRAM
but fails to find and read it from your storage media.
Please try the latest U-Boot from git. It is about to be released as
v2016.09 in a week and you have a good chance to make sure that it
works perfectly for you. There were recent changes, which rework the
boot source detection a bit:

http://git.denx.de/?p=u-boot.git;a=commit;h=ef36d9ae1646e5aee7c1425ee507d275699a072e
There is no guarantee that it will work and I don't have the same
board as you. But if there are any problems left, they should not
be very difficult to fix.
