Why is this inline?

Why does CONFIG_NAND_SPL need its own ifdef, if it's going to produce
the same code as any other !CONFIG_SPL_BUILD build?
If your concerned with making it obvious what happens with the legacy
NAND SPL, Just have a comment after #ifdef CONFIG_SPL_BUILD that says:
/* not set with legacy CONFIG_NAND_SPL */

Space, not tab, to match the rest of the file.

The indent/alignment of continuation lines here looks odd...
