// TODO: PBL-34018 This file is a mess. We should clean it up to better chose the right functions
// and list of test cases depending on the capabilities of the platform.
// Here's a clever trick: selftest functions which may or may not be
// linked into the firmware depending on the ./waf configure settings
// (read: IMU) are redeclared as weak so that it is not a linker error
// to have missing definitions for these functions. They simply link as
// zero (null pointer). This works out perfectly as the selftest code
// considers a null function pointer to mean not-implemented, which is
// exactly the outcome we want!
