[PATCH v1 1/1] opcodes: microblaze: Add hibernate and suspend instructions

Thu Sep 28 04:19:39 GMT 2023


This patch adds the MicroBlaze hibernate and suspend instructions.

Further documentation of these instructions can be found here:
https://docs.xilinx.com/v/u/en-US/ug984-vivado-microblaze-ref

This patch also re-adds the clz, mbar, sleep, swapb and swaph
instructions which were missing from the MicroBlaze instruction
list for some reason.
