-/**
- * @brief Exotic optimization.
- * @details If defined then a CPU register is used as storage for the global
- * @p currp variable. Caching this variable in a register greatly
- * improves both space and time OS efficiency. A side effect is that
- * one less register has to be saved during the context switch
- * resulting in lower RAM usage and faster context switch.
- *
- * @note This option is only usable with the GCC compiler and is only useful
- * on processors with many registers like ARM cores.
- * @note If this option is enabled then ALL the libraries linked to the
- * ChibiOS/RT code <b>must</b> be recompiled with the GCC option @p
- * -ffixed-@<reg@>.
- * @note This option must be enabled in the Makefile, it is listed here for
- * documentation only.
