2071 6310 d 14 h jermar /trunk/ (c) versus (C)  
1998 6364 d 14 h decky /trunk/boot/arch/ add version tag to other bootloaders  
1789 6498 d 19 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 6500 d 16 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6501 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.		  
1764 6516 d 13 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1620 6535 d 17 h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1478 6541 d 4 h decky /boot/trunk/ ppc32 bootloader debugging facility  
1372 6554 d 12 h decky /boot/trunk/arch/ppc32/loader/ remove obsolete BAT framebuffer mapping  
1369 6554 d 15 h decky /boot/trunk/arch/ppc32/ support for arbitrary number of boot components for ppc32  
1219 6580 d 12 h decky /boot/trunk/arch/ppc32/ ppc32: support for loading init  
1146 6600 d 19 h decky /boot/trunk/arch/ppc32/loader/ add instruction cache flush
align framebuffer on 128K boundary
change OFW calling method
make OFW code more compatible		  
1131 6609 d 15 h decky /boot/trunk/arch/ppc32/loader/ kernel boot API change

1068 6617 d 8 h decky /boot/trunk/arch/ppc32/loader/ proper ppc32 initial memory mapping
