1783 6744 d 14 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 6751 d 15 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 6759 d 13 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).

align framebuffer on 128K boundary
change OFW calling method
make OFW code more compatible		  
1130 6852 d 16 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 6859 d 22 h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)
