You can try to use latest U-Boot at
http://git.denx.de/?p=u-boot/u-boot-socfpga.git;a=summary Wonder which USB stick that you are using?
Can you try out to disable the dcache and check whether it works?

I tried
https://github.com/altera-opensource/u-boot-socfpga, branch: master, tag: v2015.10 which seemed promising as it included Terasic board support (by Marek Vasut). The resulting image did not work (hung just after SPL executed). I am still using the SPL from the pre-made 2013.01.01 build - not sure if that matters (e.g. do these need to be replaced as a set). There a few later versions in the git repo past v2015.10, but I would have expected this one to at least boot. I'm getting further from a solution...
When I restore my 2013.01.01 build I will try disabling dcache (via# define CONFIG_SYS_DCACHE_OFF in socfpga_cyclone5.h).
Thanks,

BTW - with the pre-built image, I can read the USB stick just fine. Here is the info on it since you were curious:
