Subject: [PATCH 05/16] target/mips/cpu: Set default CPU frequency to 200 MHz
Date: Mon, 28 Sep 2020 19:15:28 +0200 [thread overview]
Message-ID: <20200928171539.788309-6-f4bug@amsat.org> (raw)
In-Reply-To: <20200928171539.788309-1-f4bug@amsat.org>
Since the introduction of the 'r4k' machine in commit 6af0bf9c7c3,
the MIPS target assumes a CPU running at 200 MHz.
