Never tried with a imx25, but it looks correct and there is enough space between kernel and DT to avoid some corruption. > ## Booting kernel from Legacy Image at 81000000 ... > Image Name: Linux-3.10.0 > Image Type: ARM Linux Kernel Image (uncompressed) > Data Size: 3834336 Bytes = 3.7 MiB > Load Address: 80008000 > Entry Point: 80008000 > Verifying Checksum ...

I cannot say a lot - it seems more an issue inside the dts file as how you start the kernel. Maybe you can look in the _log_buf if you get some more info.
