Hi,
Most featureful boards, such as the Cubietruck, have been broken since the release 2017.09.
This is due to a size increase of the binary that will trip us across the size we've been using in the u-boot-sunxi-with-spl.bin file.
We would have two ways to work around it. The first one would be to just increase the offset of the environment. However, since it would break all the environments of our users and possibly the custom partition scheme that they would have created, it doesn't really seem like a smart move.
Another one would be to start trimming down a bit our enabled options in order to reduce the size and to gain some extra space for users customisations. I've taken care some of the low hanging fruits, and we should probably take another go at it in the future (and add a size check in the image build somehow?)
How about we add the size check first before crippling the feature set of sunxi boards? Then maybe rather disable lesser used features than efi_loader?
All the features have some users. All the kind of arguments that have been sent so far are that "but I use this feature". Yes. You probably do. But you can have the same kind of argument for any of the features enabled.
I agree, but my first statement still holds: Please make sure we don't overrun our size restrictions first so that these issue get caught early during the development cycle, not when U-Boot is already released.
That said, how about we just imply SYS_THUMB_BUILD in ARCH_SUNXI? That way we save even more (going from 537K to 417K with gcc7.1) without losing any feature set on 32bit systems.
