3861 5804 d 6 h decky /trunk/boot/ more exact RGB323 palette calculation
set the RGB323 palette on ppc32		  
3826 5809 d 3 h decky /trunk/boot/genarch/ call mmu_translate with corrent number of arguments  
3692 5858 d 22 h rimsky /trunk/ Fixed the bug when on SunBlade1500 we wrote to an address outside the framebuffer memory. A nasty hack to the 8-bit palette so that on sb1500 we do not have to turn black into white and white into black.  
3678 5862 d 20 h rimsky /trunk/boot/ Initialize the color palette for the 8-bit color depth on sparc64 framebuffers.  
3672 5863 d 23 h jermar /trunk/ Merge sparc branch to trunk.  
2250 6463 d 23 h jermar /trunk/boot/ Fix ticket #31.  
2071 6551 d 23 h jermar /trunk/ (c) versus (C)  
2048 6584 d 0 h jermar /trunk/ Formatting and indentation changes.  
1977 6613 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 6640 d 0 h decky /trunk/boot/genarch/ add OFW quiesce command  
1899 6665 d 6 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 6670 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 6672 d 0 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6679 d 6 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 6740 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 6740 d 4 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 6742 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6742 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 6748 d 6 h jermar /boot/trunk/ Fix ofw.c to support map and translate methods even on 64-bit platforms.  
1772 6749 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 6750 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 6757 d 22 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1755 6763 d 7 h decky /boot/trunk/arch/ppc32/loader/ read macio address from PCI OFW entry  
1620 6777 d 2 h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1146 6842 d 4 h decky /boot/trunk/arch/ppc32/loader/ add instruction cache flush
align framebuffer on 128K boundary
change OFW calling method
make OFW code more compatible		  
1130 6851 d 1 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 6858 d 7 h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)		  
1058 6859 d 1 h decky /boot/trunk/arch/ppc32/loader/ relocate kernel in real mode  
964 6861 d 10 h decky /boot/trunk/arch/ppc32/loader/ ofw code cleanup
get memory map from ofw		  
956 6861 d 23 h decky /boot/trunk/arch/ppc32/loader/ relocate ppc32 kernel above 2 GB  
953 6862 d 1 h decky /boot/trunk/arch/ppc32/loader/ cleanup and extend OFW code  
885 6877 d 7 h decky /boot/trunk/ move ppc32 boot loader to /boot tree
