Subject: [PATCH 03/25] tests: Add a simple test of the CMSDK APB timer
Date: Thu, 21 Jan 2021 19:06:00 +0000 [thread overview]
Message-ID: <20210121190622.22000-4-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210121190622.22000-1-peter.maydell@linaro.org>
Add a simple test of the CMSDK APB timer, since we're about to do
some refactoring of how it is clocked.
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
