This will increase the u-boot proper size and marginally increase the
boot time (because of a bigger binary to be read from the eMMC).

Apart of that do you expect any other impact on those changes? SPL
binary size should not be affected, correct?

Asking this out loudly to confirm that nothing unexpected is going to
happen because of these changes.

For my curiosity, care to share what's the use case? Do you plan to have
the OS stored into an NVME device?
