We could cut out some bytes by making the large/small page distinction at compile-time rather than runtime. Also, some of the strings could be cut down in size, and we could use raw accessors plus explicit barriers.
It would seem that the drivers/serial/ns16550.c file currently being included in my project has a few functions that are completely unused by my board. Is it allowable to duplicate the two functions I do use (NS16550_putc and NS16550_init) in my code within a #ifdef CONFIG_NAND_SPL? This saves about 120 (decimal) bytes in the bootstrap image.
