Subject: [PATCH 1/4] target/xtensa: add translation for wsr.mpucfg
Date: Thu, 11 Jan 2024 20:21:25 -0800 [thread overview]
Message-ID: <20240112042128.3569220-2-jcmvbkbc@gmail.com> (raw)
In-Reply-To: <20240112042128.3569220-1-jcmvbkbc@gmail.com>
Although MPUCFG is not writable, the opcode wsr.mpucfg is defined and it
just does nothing. Define wsr.mpucfg as nop.
