Since we're no longer extracting the env from the target ELF file (since upstream wouldn't take that change), we're back to the problem of cpu defines not properly propagating to the env setup stage. So the embedded env built by the host compiler doesn't match the one that is linked into the u-boot env. Reported-by: Vivi Li <vivi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
