This series reworks TLSF a bit, so we always have at least 8 byte alignment. dlmalloc already has 8 byte alignment minimum, so nothing to do there. This has the added benefit of giving TLSF the same alignment as KASAN, which can make debugging easier. v1 didn't actually manage to boot on an i.MX6, which v2 fixes. This also boots normally on i.MX8M. I suggest this going into next after v2023.09.0. v1 -> v2: - drop switch of test_ffs_fls to bselftest. This function should just be replaced with barebox' own implementation in future - keep block size a size_t and just ensure the block metadata is correctly aligned.
