Subject: [PATCH 16/18] target/riscv: Drop priv level check in mseccfg predicate()
Date: Tue, 14 Feb 2023 12:12:49 +0800 [thread overview]
Message-ID: <20230213180215.1524938-17-bmeng@tinylab.org> (raw)
In-Reply-To: <20230213180215.1524938-1-bmeng@tinylab.org>
riscv_csrrw_check() already does the generic privilege level check
hence there is no need to do the specific M-mode access check in
the mseccfg predicate().
With this change debugger can access the mseccfg CSR anytime.
