Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.

/trunk/kernel/genarch/src/ofw/
Rewrite OFW device tree traversal algorithms to iterate over the list of peers rather than recurse on each
peer node. This saves us from big troubles with stack overflows.
1972
6492 d 15 h

/trunk/
Modify selected function to consume less stack space.
Avoid flushw instruction in the sparc64 loader.

Separate mapping of EBUS interrupts into two parts: EBUS and PCI.
1911
6522 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.

Rename INO to INR, for the sake of consistency with manuals.
1909
6526 d 8 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.
1908
6528 d 18 h
jermar
/trunk/kernel/genarch/
Add function to find OFW tree node by handle.

sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree
1898
6533 d 8 h
jermar
/trunk/kernel/
Support for FFB (Creator 3D) framebuffer detection on sparc64.
(Not tested as the Ultra 60, which I have for testing, and which
only has this type of framebuffer doesn't boot for some unknown reason.)
1897
6535 d 16 h
jermar
/trunk/
Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.
1896
6536 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.

More ofw_tree work and fixes.
Add ofw_tree_lookup().
Every ofw_tree_node now also contains a disambigued name which is essential for tree lookups.

Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations
More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree
sparc64 boot:
- pass OFW device tree root node pointer to kernel
