3665 5829 d 5 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3343 5934 d 12 h decky /branches/sparc/ add sparc branch  
2745 6108 d 17 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2071 6514 d 8 h jermar /trunk/ (c) versus (C)  
1912 6616 d 17 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6617 d 6 h jermar /trunk/kernel/ 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.		  
1910 6620 d 6 h jermar /trunk/kernel/ Rename INO to INR, for the sake of consistency with manuals.  
1909 6621 d 7 h jermar /trunk/ Extend the OFW device tree node with a void pointer. The boot loader is
supposed to reset all pointers in all nodes. The kernel uses the pointer
to recognize that a particular device has already been visited and initialized.

Read interrupt mapping from the OFW device tree for FHC devices (z8530) and
EBUS devices (ns16550). In case of FHC devices, remove hardwired values from
the code and use only values read from the tree. FHC initialization is started
when a FHC device wants to map its interrupt. In case of EBUS devices, map
the interrupt to INO. Interrupt enabling in the interrupt controller for that
specific interrupt is not implemented yet.		  
1896 6631 d 7 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.
