Subject: image: Create a function to do manual relocation
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=2ac00c050582389e667374bccc5cc19b4fce80f5;p=u-boot.git

image: Create a function to do manual relocation

Rather than adding an #ifdef and open-coding this calculation, add a
helper function to handle it. Use this in the image code.
