# The following variables must be defined by a platform spec file:

# L4SYS_ARM_CPU - Platform identifiert used for constructing l4sys path
# names corresponding to the ARM platform. For example,
# specify 'arm_int' for the ARM integrator board.
# RAM_BASE - Start address of physical memory. If not specified,
# the start adress 0x0 is used.
