One advantage of the current nand_spl subsystem is that it uses the same NAND board/platform driver as the "normal", full blown U-Boot NAND subsystem does. So there is no need to maintain multiple NAND drivers for one board/platform.
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.
So again, please try to use the current nand_spl infrastructure. Or at least explain why it doesn't work for you, so that we can work on these problems.
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().
