1789 6768 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 6770 d 16 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6771 d 13 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.

1369 6824 d 14 h decky /boot/trunk/arch/ppc32/ support for arbitrary number of boot components for ppc32  
1219 6850 d 12 h decky /boot/trunk/arch/ppc32/ ppc32: support for loading init  
1146 6870 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 6879 d 15 h decky /boot/trunk/arch/ppc32/loader/ kernel boot API change  
1130 6879 d 16 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 6886 d 21 h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)		  
1068 6887 d 8 h decky /boot/trunk/arch/ppc32/loader/ proper ppc32 initial memory mapping  
1058 6887 d 15 h decky /boot/trunk/arch/ppc32/loader/ relocate kernel in real mode  
1022 6888 d 16 h decky /boot/trunk/arch/ppc32/loader/ ppc32: boot using real mode trampoline
setup segment registers so far		  
986 6889 d 17 h decky /boot/trunk/arch/ppc32/loader/ ppc32: support for exception vectors  
981 6889 d 19 h decky /boot/trunk/arch/ppc32/loader/ temporal CUDA (VIA 6805) mapping  
971 6889 d 23 h decky /boot/trunk/arch/ppc32/loader/ ppc32: move kernel one frame up
