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.
