11  * Warning, horror ahead.
12  *
13  * The target code lives in our "secure ram", but u-boot doesn't know
14  * that, and has blindly added reloc_off to every relocation
15  * entry. Gahh. Do the opposite conversion. This hack also prevents
16  * GCC from generating code veeners, which u-boot doesn't relocate at
17  * all...
