    55Various non BSP dependant support routines.
    66
    7 clock - Uses the 403 PIT (Programmable interval timer) to
     7clock - Uses the MPC860 PITPIT (Programmable interval timer) to
    88        generate RTEMS clock ticks.
    99
    10 console - Uses the 403 Internal serial port to do RTEMS
    11         console I/O.  Not ALL members of the 403 family
    12         have this.
     10console_generic - Uses the MPC860 SCCs and SMCs to to serial I/O
    1311
    14 include - Currently empty
     12include - console.h: function declarations for console related functions
    1513
    16 timer - Uses the 403 timebase register for timing
    17         tests.  Other PowerPCs have slightly different
    18         timebase register definitions.
     14timer - Uses the MPC860 timebase register for timing
     15        tests.  It only uses the lower 32 bits
    1916
    20 vectors - PowerPC 403 specific vector entry points.
     17vectors - MPC860 specific vector entry points.
    2118        Includes CPU dependant, application independant
    2219        handlers: alignment.

    1111  How this is achieved is dependant on the tool chain.

    13   However the basic mechanism for ELF assemblers is to create a
    14   section called ".vectors", which will be loaded to an address
    15   between 0x????0000 and 0x????0100 (inclusive) via a link script.
    16 
    17   The basic mechanism for XCOFF assemblers is to place it in the
    18   normal text section, and arrange for this file to be located
    19   at an appropriate position on the linker command line.

    2115  The variable 'PPC_VECTOR_FILE_BASE' must be defined to be the
    2216  offset from 0x????0000 to the first location in the file.  This
    23   will usually be 0x0000 or 0x0100.
     17  will be either 0x0000 or 0xfff0.

     19The eth_comm BSP defines PPC_VECTOR_FILE_BASE to be 0x00000000
