[PATCH 0/6] target/microblaze: Clean up MMU translation failed path

[Philippe Mathieu-Daudé]

Hi Edgar,

While reviewing/auditing how each arch handles failed MMU
transactions, I noticed some confusing code regarding the
On-chip Peripheral Bus (OPB) interface which is currently
not implemented. I took some notes and re-ordered the code
a bit, resulting in this series.

Q: Should we exit gracefully in mb_cpu_realizefn() if the
user requests features that are not implemented?

Thanks,

Phil.
