Well, as already said this is related to CRC calculation of environment. I did a fast port to v2011.03 and the setenv is a lot faster, which is due the new env code base. But I also noticed the time until kernel_entry is called is about 30ms later after reset than on the old code base. But I didn't investigate any time further to see what caused this. But AFAICS also the new U-Boot code doesn't enable dcache on ARM1136 either.
This is wrong. The dcache is enabled on several MX31 boards. On the mx35pdk, it is not enabled.
Add CONFIG_CMD_CACHE to your configuration file, and you will get the dcache <on|off> command.
