# 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.
