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.
