# Requirements:
#
# CHIBIOS:			The location of the ChibiOS code	eg CHIBIOS=../chibios
# CHIBIOS_PLATFORM	The name of the ChibiOS platform	eg CHIBIOS_PLATFORM=AT91SAM7
# CHIBIOS_PORT		The name of the ChibiOS port		eg CHIBIOS_PORT=GCC/ARM/AT91SAM7
# CHIBIOS_CPUCLASS  The class of the CPU. Only required for ChibiOS v3   eg CHIBIOS_CPUCLASS=ARMCMx
#

# Optional:
#
# CHIBIOS_LDSCRIPT	The name of the loader script		eg CHIBIOS_LDSCRIPT=AT91SAM7X256.ld
# CHIBIOS_BOARD		The name of the ChibiOS board		eg CHIBIOS_BOARD=OLIMEX_SAM7_EX256 - if not specified you must include equivalent code yourself
# CHIBIOS_STM32LIB	Use the STM32 library source for drivers instead of native drivers (yes or no) - default no
# CHIBIOS_VERSION	Which version of ChibiOS is this (2 or 3) - default is 2
# CHIBIOS_PROCESS_STACKSIZE     Size of the ChibiOS process stack. Only useful if the link script supports it - default is 0x400
# CHIBIOS_EXCEPTIONS_STACKSIZE  Size of the ChibiOS exceptopms stack. Only useful if the link script supports it - default is 0x400
