Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.

Formatting and indentation changes.

Fix bad indentation in ofw.c
sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.

Rewrite ofw_tree_node_process() to iterate through the peer list instead of recursing.

add OFW quiesce command

/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.

Add node handle to in-memory ofw tree node.
This is essential for interrupt mapping on sparc64
and perhaps on other platforms that have OpenFirmware.

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
1896

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.
1895

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.
1894

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
1893
6548 d 7 h
jermar
/trunk/boot/
Add prototype implementation for creating canonical copy of OpenFirmware device tree.
1881
6555 d 13 h
jermar
/trunk/
sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places
OpenFirmware work:
- two new functions for walking the device tree
Generic boot loader work:
- added basic string functions
Usual pile of indentation and formatting fixes.

Remove OpenFirmware calls from kernel/ entirely.
Switch the sparc64 port to use bootinfo.
Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.

Fix ofw_memmap() in boot infrastructure.
The cell size is 32-bit and not equal sizeof(ofw_arg_t).
Define architecture dependant #address-cells and #size-cells for cases
the respective properties are missing in the OpenFirmware device tree.
The algorithm now works both for ppc32 and sparc64.
Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure.
Be more verbose during sparc64 boot.
Move ALIGN_UP to generic part of boot/.
Change header guards in several places so that they don't contain double underscore.
