# Config file for a PowerPC MPC821- or MPC860-based MBX card
#
# This file is derived from:
#
# Config file for a PowerPC 403 based helas403 card
# Config file for MPC860 based Ethernet Comm Board
#
include $(RTEMS_ROOT)/make/custom/default.cfg
RTEMS_CPU=powerpc
RTEMS_CPU_MODEL=mpc8xx
# This is the actual bsp directory used during the build process.
RTEMS_BSP_FAMILY=mbx8xx
# The value assigned to RTEMS_CPU, RTEMS_CPU_MODEL and RTEMS_BSP get
# #defined in targopts.h. Source code can switch on these values with #ifdef
# to select what code to compile for a specific CPU family member and specific
# board. The RTEMS_CPU_MODEL is also used as the name of the libcpu directory,
# while the RTEMS_BSP_FAMILY is used as the name of the libbsp directory.
# For the MBX860 and MBX821, the boards and processors are sufficiently
# similar that the ports are unified and use RTEMS_CPU_MODEL=mpc8xx and
# RTEMS_BSP_FAMILY=mbx8xx. Because there are minor differences in the CPUs
# and the boards, it is necessary to specify them fully during the build.
# Do a "make RTEMS_BSP=<your_board> <target>" See below for a list of valid
# values for <your_board>.

# Note that RTEMS_BSP matches the RTEMS_MBX_MODEL. Its value must be

# for different MBX models can be distinguished. The value of

# mbx860_001 mbx821_001
# mbx860_002 mbx821_002
