According to these e-mails:
http://lists.denx.de/pipermail/u-boot/2007-October/025937.html
http://lists.denx.de/pipermail/u-boot/2007-October/025941.html
it worked in (at least some) 4.0, but not (at least some) 3.x or 4.1.
If we're now at the point where current GCC works, and has for several
releases, we should probably consider revisiting those patches.
