1783 5676d 08h 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 5683d 09h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).
 
1764 5691d 08h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1755 5696d 17h decky /boot/trunk/arch/ppc32/loader/ read macio address from PCI OFW entry  
1620 5710d 12h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1146 5775d 14h 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 5784d 11h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 5791d 16h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)
 
1058 5792d 10h decky /boot/trunk/arch/ppc32/loader/ relocate kernel in real mode  
964 5794d 20h decky /boot/trunk/arch/ppc32/loader/ ofw code cleanup

953 5795d 11h decky /boot/trunk/arch/ppc32/loader/ cleanup and extend OFW code  
885 5810d 17h decky /boot/trunk/ move ppc32 boot loader to /boot tree
