[PATCH v1 0/2] target/microblaze: Improve bus fault handling

Posted by Edgar E. Iglesias 5 years, 2 months ago

From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>

Richards recent MicroBlaze patches exposed a bug in
the MB ports bus fault handling. If the core is not
setup for exceptions, we clobber the CPU state when
preparing to raise one. This fixes the bug.

Best regards,
Edgar
