Does this patch fix your problem?

---8<---
The patch that added src_dma/dst_dma to struct mv_cesa_tdma_desc
is broken on 64-bit systems as the size of the descriptor has been
changed.  This patch fixes it by using u32 instead of dma_addr_t.

Fixes: e62291c1d9f4 ("crypto: marvell/cesa - Fix sparse warnings")

Yes, it fixes the problem and also the failing hash test.

Thanks and best
