Hi kuldeep nigam,
I think you want to change CONFIG_SYS_MONITOR_LEN in your
configs/board/*.h board config file. Based on the numbers above, you
should be able to reduce it to 256K.
* You want it to be a multiple of a flash sector in size.
* Your environment is probably stored in the next flash sector.
* The change doesn't actually change the size of u-boot, it just
changes the amount of padding in the .bin file.
The README file could probably stand some tuning.

Best regards,
