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.
This is an essential feature for booting OpenBSD. And I believe it is a requirement for several Linux distros as well. I don't think disabling this by default is a good idea.
How much of that 31kB is due to recent improvements of the EFI loader support? I understand the desire to have a more complete EFI implementation, but if the consequence of that is that the EFI loader gets disabled by default on many boards I think we're throwing out the baby with the bathwater...
