21#  PPC_VECTOR_FILE_BASE (PowerPC)
22#     This defines the base address of the exception table.
23#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
24#       
25#  PPC_ABI (PowerPC)
26#     This defines the calling convention (Application Binary Interface)
27#     used in this configuration.  EABI is the only one supported.
28#     This BSP was initially developed using the PowerOpen ABI.
29#
30#  PPC_ASM (PowerPC)
31#     This defines the assembly language format used in this configuration.
32#     ELF is the only one supported.
33#
34#  PPC_USE_SPRG (RTEMS PowerPC port)
35#     If defined (=1), then the PowerPC specific code in RTEMS will use some
36#     of the special purpose registers to slightly optimize interrupt
37#     response time.  The use of these registers can conflict with
38#     other tools like debuggers.
