-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.
