I saw correct PAD_TO value without modification.

ccache /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi-objcopy
--gap-fill=0xff --pad-to=4096 -O binary
/home/share/Work/u-boot-work/nand_spl/u-boot-spl
/home/share/Work/u-boot-work/nand_spl/u-boot-spl-16k.bin

and I've got 4Kbyte binary also.

-rwxr-xr-x  1 prom prom  4096 2009-09-16 10:21 u-boot-spl-16k.bin

I think there have no problem.
If it's not your problem, please explain in more detail.

Thanks.
