  • 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.
