Subject: [PATCH 12/16] hw/mips/boston: Set CPU frequency to 1 GHz
Date: Mon, 28 Sep 2020 19:15:35 +0200 [thread overview]
Message-ID: <20200928171539.788309-13-f4bug@amsat.org> (raw)
In-Reply-To: <20200928171539.788309-1-f4bug@amsat.org>
The I6400 can run at 1 GHz or more. Create a 'cpuclk'
output clock and connect it to the CPU input clock.
