Vignesh, Thank you very much.

I am not familiar with the liker script.
Can I simplely modify the following codes in u-boot.lds
	. = 0xff00;
 	.start16 : AT (0x05ffff00) { *(.start16); }
 
 	. = 0xfff0;
 	.reset : AT (0x05fffff0) { *(.reset); }

To 
	. = 0xff00;
 	.start16 : AT (0x06ffff00) { *(.start16); }
 
 	. = 0xfff0;
 	.reset : AT (0x06fffff0) { *(.reset); }

The compilation is Ok, but the file size is 26M, it is very large.

Can you told me how to change the lds file. Thanks very much
