-Various non BSP dependant support routines.
-
-clock - Uses the 403 PIT (Programmable interval timer) to
-	generate RTEMS clock ticks.
-
-console - Uses the 403 Internal serial port to do RTEMS
-	console I/O.  Not ALL members of the 403 family
-	have this.
-
-include - Currently empty
-
-timer - Uses the 403 timebase register for timing
-	tests.  Other PowerPCs have slightly different
-	timebase register definitions.
-
-vectors - PowerPC 403 specific vector entry points.
-	Includes CPU dependant, application independant
-	handlers: alignment.

-The location of the vectors file object is critical.
-
-From the comments at the head of vectors.s:
-
-  The issue with this file is getting it loaded at the right place.
-  The first vector MUST be at address 0x????0100.
-  How this is achieved is dependant on the tool chain.
-
-  However the basic mechanism for ELF assemblers is to create a
-  section called ".vectors", which will be loaded to an address
-  between 0x????0000 and 0x????0100 (inclusive) via a link script.
-
-  The basic mechanism for XCOFF assemblers is to place it in the
-  normal text section, and arrange for this file to be located
-  at an appropriate position on the linker command line.
-
-  The variable 'PPC_VECTOR_FILE_BASE' must be defined to be the
-  offset from 0x????0000 to the first location in the file.  This
-  will usually be 0x0000 or 0x0100.
