Subject: [PATCH 25/25] hw/arm/stellaris: Remove board-creation reset of STELLARIS_SYS
Date: Thu, 21 Jan 2021 19:06:22 +0000
Message-ID: <20210121190622.22000-26-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210121190622.22000-1-peter.maydell@linaro.org>

Now that the watchdog device uses its Clock input rather than being
passed the value of system_clock_scale at creation time, we can
remove the hack where we reset the STELLARIS_SYS at board creation
time to force it to set system_clock_scale.  Instead it will be reset
at the usual point in startup and will inform the watchdog of the
clock frequency at that point.
