2307 6405 d 22 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2131 6449 d 3 h decky /branches/ add development branches  
2071 6514 d 23 h jermar /trunk/ (c) versus (C)  
2048 6547 d 1 h jermar /trunk/ Formatting and indentation changes.  
1977 6576 d 20 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.		  
1947 6603 d 0 h decky /trunk/boot/genarch/ add OFW quiesce command  
1899 6628 d 7 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		  
1895 6633 d 23 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.		  
1893 6635 d 1 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6642 d 7 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.		  
1790 6703 d 2 h jermar /trunk/ 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.		  
1789 6703 d 5 h jermar /trunk/ 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.		  
1787 6705 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6705 d 23 h jermar /boot/trunk/ Some 32-bit vs. 64-bit fixes.

Make the call to OpenFirmware client interface architecture dependent.
For instance and contrary to my previous experience, the sparc64 version of
'translate' method would not work reliably unless the Address Mask bit in the
PSTATE register is cleared during duration of the call.

sparc64 and ppc32 OpenFirmware seem to differ in details, for example, the above
mentioned method 'translate' signals success by setting the first return value
to -1 on sparc64 while on ppc32 the value is/stays (???) zero.		  
1782 6711 d 6 h jermar /boot/trunk/ Fix ofw.c to support map and translate methods even on 64-bit platforms.  
1772 6712 d 21 h jermar /boot/trunk/genarch/ Last changes to make ofw.c work for both 32-bit and 64-bit architectures during boot.  
1771 6713 d 0 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 6720 d 22 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1755 6726 d 8 h decky /boot/trunk/arch/ppc32/loader/ read macio address from PCI OFW entry  
1620 6740 d 3 h decky /boot/trunk/arch/ppc32/loader/ update boot loader API
