One way to solve this would be to change the dependency to config POWER_RESET_BRCMSTB bool "Broadcom STB reset driver" depends on POWER_RESET && ARM depends on ARCH_BRCMSTB || COMPILE_TEST which in effect would allow building it on any ARM machine as long as COMPILE_TEST is set (which normally is not). The same could be expressed using config POWER_RESET_BRCMSTB bool "Broadcom STB reset driver" if COMPILE_TEST depends on POWER_RESET && ARM My preference in this case however would be to just drop the 'select' statement and add the driver to the defconfig file.
