Merge tag 'fixes-against-v3.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Merge "omap fixes against v3.18-rc2" from Tony Lindgren:

Few fixes for omaps to enable NAND BCH so devices won't
produce errors when booted with omap2plus_defconfig, and
reduce bloat by making IPV6 a loadable module.

Also let's add a warning about legacy boot being deprecated
for omap3.

We now have things working with device tree, and only omap3 is
still booting in legacy mode. So hopefully this warning will
help move the remaining legacy mode users to boot with device
tree.

As the total reduction of code and static data is somewhere
around 20000 lines of code once we remove omap3 legacy mode
booting, we really do want to make omap3 to boot also in
device tree mode only over the next few merge cycles.
