[U-Boot] Code relocation in U-boot.

[Sandeep Sharma]

Hi,

You are absolutely right. I am talking about ARM code located in start.S
file.
I am not able to figure out from from the referred link. I also consulted "
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044d/IHI0044D_aaelf.pdf
"
which talks about arm code relocation but it is also not helpful. It
nowhere talks about ".rel.dyn" section which i referred to in my previous
post. Can You provide any pointer from where i can get understanding of
this section.

Regards,,
Sandeep
