I would suggest going with upstream/master (targeting 2015.07) since
there are several driver model changes since 2015.04 (USB, PCI,
Ethernet). There are still patches going in but the bulk of it should
be there.

Masahiro is the expert here. The idea is to use SPL-specific options
for SPL. For example CONFIG_SPL_I2C_SUPPORT. This is much the same as
before.

I suggest you create some SPL options for your new features, so that
they are only enabled in SPL when you want them.

Also, if you push your tree to github (or somewhere) I or Masahiro
might be able to comment on specifics.
