From 065b8ced7c40bd6a4444f7005413f7af9fe6b642 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 11 May 2022 15:35:50 +0200 Subject: [PATCH] openrisc: remove bogus nops and shutdowns 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 impossible to handle errors. Cc: Stafford Horne Signed-off-by: Jason A.
