3674 5637 d 6 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
2927 5841 d 18 h decky /branches/dynload/ added dynload branch  
2467 6178 d 10 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6183 d 13 h jermar /trunk/ Merge arm32 into trunk.  
2250 6237 d 7 h jermar /trunk/boot/ Fix ticket #31.  
2071 6325 d 8 h jermar /trunk/ (c) versus (C)  
2048 6357 d 9 h jermar /trunk/ Formatting and indentation changes.  
1977 6387 d 4 h jermar /trunk/ Fix bad indentation in ofw.c

sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.		  
1973 6397 d 8 h jermar /trunk/boot/genarch/ Rewrite ofw_tree_node_process() to iterate through the peer list instead of recursing.  
1947 6413 d 9 h decky /trunk/boot/genarch/ add OFW quiesce command  
1909 6432 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.		  
1907 6434 d 18 h jermar /trunk/ 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.		  
1899 6438 d 15 h jermar /trunk/ 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 6442 d 6 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.		  
1895 6444 d 8 h jermar /trunk/ 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 6445 d 5 h jermar /trunk/ 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 6445 d 9 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6452 d 15 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.
