3343 5930 d 11 h decky /branches/sparc/ add sparc branch  
2071 6510 d 7 h jermar /trunk/ (c) versus (C)  
1789 6698 d 13 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 6700 d 10 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6701 d 7 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.		  
1214 6780 d 8 h decky /boot/trunk/arch/ppc32/loader/ initially fill segment registers

885 6835 d 16 h decky /boot/trunk/ move ppc32 boot loader to /boot tree
