charset="utf-8" Currently the CMSDK APB watchdog tests target an specialized version of the device (luminaris using the lm3s811evb machine) that prevents the development of tests for the more generic device documented in: https://developer.arm.com/documentation/ddi0479/d/apb-components/apb-watchd= og/programmers-model This patch allows the execution of the watchdog tests in an MPS2 machine (when applicable) which uses the generic version of the CMSDK APB watchdog. Finally the rules for compiling the test have to change because it is possible not to have CONFIG_STELLARIS (required for the lm3s811evb machine) while still having CONFIG_CMSDK_APB_WATCHDOG and the test will fail. Due to the addition of the MPS2 machine CONFIG_MPS2 becomes also a dependency for the test compilation.
