From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jason A. Donenfeld Date: Wed, 4 May 2022 13:09:11 +0200 Subject: [PATCH] openrisc: remove bogus nops and shutdowns Message-ID: <20220504110911.283525-1-Jason@zx2c4.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: openrisc@lists.librecores.org Nop 42 is some leftover debugging thing by the looks of it. Nop 1 will shut down the simulator, which isn't what we want, since it makes it possible to handle errors. Cc: Stafford Horne Signed-off-by: Jason A.
