18# The value assigned to RTEMS_CPU, RTEMS_CPU_MODEL and RTEMS_BSP get
19# #defined in targopts.h. Source code can switch on these values with #ifdef
20# to select what code to compile for a specific CPU family member and specific
21# board. The RTEMS_CPU_MODEL is also used as the name of the libcpu directory,
22# while the RTEMS_BSP_FAMILY is used as the name of the libbsp directory.
23# For the MBX860 and MBX821, the boards and processors are sufficiently
24# similar that the ports are unified and use RTEMS_CPU_MODEL=mpc8xx and
25# RTEMS_BSP_FAMILY=mbx8xx. Because there are minor differences in the CPUs
26# and the boards, it is necessary to specify them fully during the build.
27# Do a "make RTEMS_BSP=<your_board> <target>" See below for a list of valid
28# values for <your_board>.
