1783 5669d 14h 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 5676d 15h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).
 
1764 5684d 13h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1755 5689d 23h decky /boot/trunk/arch/ppc32/loader/ read macio address from PCI OFW entry  
1620 5703d 17h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1146 5768d 19h 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 5777d 16h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 5784d 22h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)
 
1058 5785d 16h decky /boot/trunk/arch/ppc32/loader/ relocate kernel in real mode  
964 5788d 01h decky /boot/trunk/arch/ppc32/loader/ ofw code cleanup

953 5788d 16h decky /boot/trunk/arch/ppc32/loader/ cleanup and extend OFW code
