Last change on this file since 2b017ba was e2cc9a0, checked in by Jakub Jermar <jakub@…>, 19 years ago

Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers.
