I theoretically don't have anything against that, but if I do this change in U-Boot, and then use U-Boot to reflash to NAND the SPL and U-Boot itself, will the OMAP ROM code still be able to read the SPL from NAND ? I'm not sure which ECC scheme does the OMAP ROM code support, and how it detects (or not) which ECC scheme to use to read the SPL.
