As Wolfgang pointed out, this doesn't belong here.  Create your own
alternate SPL driver if your hardware doesn't work with the simple one
(similar to the not-yet-migrated nand_spl/nand_boot_fsl_elbc.c,
nand_spl/nand_boot_fsl_ifc.c, etc).

Please refrain from making random unrelated whitespace changes in a
patch that also makes functional changes, particularly when they are
extensive enough to make it hard to spot the functional changes.

In this particular case, I think the whitespace was fine the way it was;
the continuation lines were nicely aligned.
