One minor nitpick, apart from that - LGTM.

[wargio]

please revert the formatting changes on z80.c and riscv.c
Those files are from GPL sources and should keep the same formatting.

@wargio are you sure about z80.c? It seems LGPL one and uses sdb_fmt heavily. I think it should not be excluded from formatting checks

@HN026, please proceed with changes in z80 and remove that directory from sys/clang-format.py skiplist.
