   8 * Warning, horror ahead.
   9 *
  10 * The target code lives in our "secure ram", but u-boot doesn't know
  11 * that, and has blindly added reloc_off to every relocation
  12 * entry. Gahh. Do the opposite conversion. This hack also prevents
  13 * GCC from generating code veeners, which u-boot doesn't relocate at
  14 * all...
