# The value assigned to RTEMS_CPU, RTEMS_CPU_MODEL and RTEMS_BSP get

# board. The RTEMS_CPU_MODEL is also used as the name of the libcpu 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.
