3397 6375 d 9 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3343 6399 d 6 h decky /branches/sparc/ add sparc branch  
2071 6979 d 2 h jermar /trunk/ (c) versus (C)  
1799 7163 d 23 h decky /trunk/boot/arch/ppc32/loader/ fix typo  
1789 7167 d 8 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 7169 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 7170 d 2 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 7177 d 3 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 7185 d 1 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1755 7190 d 11 h decky /boot/trunk/arch/ppc32/loader/ read macio address from PCI OFW entry  
1620 7204 d 6 h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1146 7269 d 8 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 7278 d 4 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 7285 d 10 h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)		  
1058 7286 d 4 h decky /boot/trunk/arch/ppc32/loader/ relocate kernel in real mode  
964 7288 d 14 h decky /boot/trunk/arch/ppc32/loader/ ofw code cleanup
get memory map from ofw		  
956 7289 d 3 h decky /boot/trunk/arch/ppc32/loader/ relocate ppc32 kernel above 2 GB  
953 7289 d 4 h decky /boot/trunk/arch/ppc32/loader/ cleanup and extend OFW code  
885 7304 d 10 h decky /boot/trunk/ move ppc32 boot loader to /boot tree
