Subject: [PATCH v1 1/1] opcodes: microblaze: Add hibernate and suspend instructions
Date: Thu, 28 Sep 2023 05:19:39 +0100 [thread overview]
Message-ID: <20230928041939.2238068-1-neal.frager@amd.com> (raw)
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.
