4537 5461 d 4 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4536)  
4296 5520 d 20 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4295)  
4055 5560 d 0 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 5843 d 2 h decky /branches/dd/ device drivers branch  
2745 5935 d 1 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2071 6340 d 17 h jermar /trunk/ (c) versus (C)  
1974 6411 d 19 h jermar /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 6413 d 23 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1908 6450 d 2 h jermar /trunk/kernel/genarch/ Add function to find OFW tree node by handle.  
1899 6454 d 0 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 6457 d 16 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 6459 d 17 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 6460 d 15 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
