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.
