[U-Boot] U-boot changes

[JYOTI DUBEY]

Hi,
I am trying to perform secure booting on nitrogen6x SOM.After compiling the
u-boot2013.08 source code I have obtained a u-boot.imx image with fsize
51c00.I tried to pad and sign this image for authentication which returns
me a u-boot-signed-padded.imx. The problem is that the size of this new
image is still the same i.e 51c00 which impiles that actually no change is
happening to u-boot.imx. I tried making some chage u-boot.lds file to
attach HAB data but it did not work.How can this problem be solved?

Thanks in Advance!
