3665	5678 d 19 h	rimsky	/branches/sparc/	Merged latest trunk changes into the sparc brach.
3343	5784 d 1 h	decky	/branches/sparc/	add sparc branch
2745	5958 d 6 h	decky	/trunk/	code cleanup (mostly signed/unsigned) allow extra compiler warnings
2071	6363 d 21 h	jermar	/trunk/	(c) versus (C)
1912	6466 d 7 h	jermar	/trunk/kernel/	Separate mapping of EBUS interrupts into two parts: EBUS and PCI.
1911	6466 d 19 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	6469 d 19 h	jermar	/trunk/kernel/	Rename INO to INR, for the sake of consistency with manuals.
1909	6470 d 21 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	6480 d 20 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.
