For my ppc405EP based custom board I would like to make few changes to the u-boot memory map, so that every time I update the u-boot, environment variables in the flash remain untouched.

Now isn't this a very precise error message? Which other hints do you need?
Where am I going wrong??
Your whole approach seems overkill to me. Why don;t you simply include a "saveenv" command in your update script? As long as the environment is not shifted (which seems unlikelyin your case) no other changes are needed.
