1783 6746 d 16 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.
 
1782 6751 d 23 h jermar /boot/trunk/ Fix ofw.c to support map and translate methods even on 64-bit platforms.  
1772 6753 d 14 h jermar /boot/trunk/genarch/ Last changes to make ofw.c work for both 32-bit and 64-bit architectures during boot.  
1771 6753 d 17 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).
 
1764 6761 d 15 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).
