This isn't the denx list; what kernel version is that, and with what 
modifications from mainline?

Note that ep88xc.dts in mainline is intended for use with PlanetCore, which is 
what ships on that board.  You may need to make modifications for it to work 
with u-boot (at the least, the IMMR base is probably different).  This is why 
u-boot should be maintaining its own repository of trees that it passes...

Also, make sure u-boot is properly updating the memory size in the device tree. 
  Can you dump the post-fixup device tree in u-boot?
