3742 5804 d 3 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3618 5837 d 16 h rimsky /branches/sparc/ Support for framebuffers, where the first pixel is mapped to a different address than the OBP 'reg' property claims. Cleanup, comments, C-style.  
3607 5838 d 15 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3582 5848 d 5 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3479 5892 d 1 h rimsky /branches/sparc/ Names containing 'UPA' replaced with strings containing more general 'ICBUS'. SMART_FIRMWARE option replaced with CPU autodetection + new option CONFIG_A_OUT_ISOFS_B.  
3467 5898 d 17 h rimsky /branches/sparc/ SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks.  
3397 5909 d 1 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5926 d 17 h rimsky /branches/sparc/ Integrated US-III port into the build process; added script for downloading and patching SILO; added patched SILO binaries; modified sources of the Sparc64 port up to the beginning of the main_bsp_separated_stack function: phys. address size not hardwired but configurable (41 bits on US-II, 43 bits on US-III), WSTATE register implicitly written 0 on startup.  
3343 5932 d 22 h decky /branches/sparc/ add sparc branch  
2467 6365 d 21 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6371 d 0 h jermar /trunk/ Merge arm32 into trunk.  
2250 6424 d 18 h jermar /trunk/boot/ Fix ticket #31.  
2071 6512 d 18 h jermar /trunk/ (c) versus (C)  
2048 6544 d 20 h jermar /trunk/ Formatting and indentation changes.  
1977 6574 d 15 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 6584 d 19 h jermar /trunk/boot/genarch/ Rewrite ofw_tree_node_process() to iterate through the peer list instead of recursing.  
1947 6600 d 19 h decky /trunk/boot/genarch/ add OFW quiesce command  
1909 6619 d 18 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 6622 d 4 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 6626 d 2 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
