The EFI loader support takes around 31kB on an ARMv7 board, which makes us trip across the size limit we've had on the U-Boot binary.
Since it's not an essential feature, disable it by default for ARCH_SUNXI so that we get back some extra room for user customisations.

Quite the contrary - it is essential. All major distributions are going for distro boot + EFI at least for 64bit platforms now. Disabling it by default means you basically kill your user base on those.
EFI is mandatory for 32 and 64 bit OpenBSD arm. I would not be surprised if others made similiar choices to be able to boot off filesystems unsupported by U-Boot and have something close to a real firmware interface.

Nack on any change to that default line. If you must disable efi_loader (and really, I strongly advise not to do so for sunxi), please do so in the defconfigs, as nothing prohibits the architecture to work with it.
