[U-Boot] Booting through nand flash with other address

[Manukumar]

Dear all,

In u-boot(u-boot-2010.12) 
1) The TEXT_BASE address is 11001000.
2) Nand Flash Erasing at Address 0x00000000 
3) Nand Flash Writing u-boot-nand.bin at address 0x00000000 
4) When Power is switched On the booting happens.

till this there is no issue, now i want to change the 
booting address to different location(ex:0x02000000)
do i want to change the TEXT_BASE address accordingly 
to boot it from 0x02000000.
like below,
 
1) The TEXT_BASE address is 0x02000000.
2) Nand Flash Erasing at Address 0x02000000 
3) Nand Flash writing u-boot-nand.bin at address 0x02000000 .

if i do as above i cant boot from nand there is no boot log messages.

Please suggest me on How can i do to boot from different location
