2307 6403 d 4 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2131 6446 d 9 h decky /branches/ add development branches  
2071 6512 d 6 h jermar /trunk/ (c) versus (C)  
1947 6600 d 7 h decky /trunk/boot/genarch/ add OFW quiesce command  
1899 6625 d 13 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 6631 d 6 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 6632 d 7 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6639 d 13 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 6700 d 9 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 6700 d 11 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 6702 d 8 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6703 d 5 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 6710 d 6 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 6718 d 5 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1620 6737 d 9 h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1146 6802 d 11 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 6811 d 8 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 6818 d 13 h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)		  
1058 6819 d 7 h decky /boot/trunk/arch/ppc32/loader/ relocate kernel in real mode  
964 6821 d 17 h decky /boot/trunk/arch/ppc32/loader/ ofw code cleanup
get memory map from ofw
