But thanks to the clean-ups that have been done during the past years, it's not that difficult anymore to finally make it possible to disable CONFIG_ARM_V7M: We just have to move some v7m-related code out of cpu32.c to a separate file (that we only compile if the switch CONFIG_ARM_V7M is enabled) and make sure to use the stub functions in m_helper.c if it is disabled. Then we can finally remove the hard-coded "select ARM_V7M" from the Kconfig file.
