3861 5754 d 5 h decky /trunk/boot/ more exact RGB323 palette calculation
set the RGB323 palette on ppc32		  
3829 5759 d 1 h decky /trunk/ use macio optionally  
3678 5812 d 19 h rimsky /trunk/boot/ Initialize the color palette for the 8-bit color depth on sparc64 framebuffers.  
2250 6413 d 22 h jermar /trunk/boot/ Fix ticket #31.  
2071 6501 d 22 h jermar /trunk/ (c) versus (C)  
1947 6589 d 23 h decky /trunk/boot/genarch/ add OFW quiesce command  
1899 6615 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 6620 d 22 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 6622 d 0 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6629 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 6690 d 1 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 6690 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 6692 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6692 d 22 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.		  
1771 6699 d 23 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 6707 d 21 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1620 6727 d 2 h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1146 6792 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 6801 d 0 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 6808 d 6 h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)
