The elbc nand driver alone is over 4K, so that's not going to work.  It
could be cut down a bit by removing erase/program support, and only
supporting the page size present on the target hardware, but even then I'd
rather use the space for things like SPD-based SDRAM initialization.

The NAND controller on the 8313 exposes a very different programming
interface than what nand_spl expects.  I don't think there's much that could
be re-used, other than the high-level functions like nand_load().
