Same remark as with the previous patch, I'm not happy to see all these
patches removing #ifdef-s given that spl is severely size constrained
on some devices (e.g. recently we had a patchset for the rockchip 3036,
which has only 8k space for the SPL).

And I really do not see a need for this, boards which want to use
multiple methods can simple define the CONFIG_SPL_FOO for all of them.

Likewise this is also not necessary to convert things to an array
of image loading functions to try one by one, which your ultimate
goal seems to be (which is a good goal). You can simply put
#ifdef's around the array initializers which are not always there.

Regards,

Hans
