Stefano,

commit 38d6b7ebdaee ("spl: Drop bd_info in the data section") is the
culprit which breaks IMX boards using SPL that don't define
SPL_ALLOC_BD. There is another thread regarding if that commit should
be reverted or if instead it can be fixed (ie by defining
SPL_ALLOC_BD) so probably not worth discussing in this thread anymore.

Best regards,

Tim
