 - FIX: Fixed broken TIM8 support in STM32 PWM driver (bug 3418620).
 - FIX: Fixed halconf.h file corrupted in some STM32 demos (bug 3418626).
 - NEW: Added memory copy functionality to the STM32 DMA driver.
+- NEW: Implemented new makefile system for ARM GCC ports, now objects,
+  listings and out files are generated into a "build" directory and not

+  Now makefiles and load stript files are requirements and trigger a
