* bootloader/Makefile.am, console/Makefile.am, pci/Makefile.am:
	Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably
	with the goal to make it more flexible and reusable by other
	BSPs. The main strategies were:
	    - eliminate hardcoded base addresses; devices use offsets
	      and a BSP defined base address.
	    - separate functionality into different files (e.g. reboot from
	      inch.c to reboot.c) which can be overridden by a 'derived' BSP.
	    - separate initialization code into separate files (e.g.  PCI
	      bridge detection/initialization was separated from the more
	      generic PCI access routines), also to make it easier for
	      'derived' BSPs to substitute their own initialization code.
	There are also a couple of enhancements and fixes:
	    - IRQ handling code now has a hook for attaching a VME bridge.
	    - OpenPIC is now explicitely initialized (polarities, senses).
	      Eliminated the implicit assumption on the presence of an ISA PIC.
	    - UART and console driver now supports more than 1 port. The current
	      maximum of 2 can easily be extended by enlarging a table (it
	      would even be easier if the ISR API was not broken by design).
	    - fixed polled_io.c so it correctly supports console on COM2
	    - fixed TLB invalidation code (start.S).
	    - exception handler prints a stack backtrace.
	    - added BSP_pciFindDevice() to scan the pci bus for a particular
	      vendor/device/instance.
