1837 6495 d 14 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.		  
1789 6517 d 7 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 6519 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6520 d 1 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.		  
1773 6527 d 0 h jermar /boot/trunk/arch/sparc64/loader/ Work on sparc64 boot loader (still inactive).  
1771 6527 d 3 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 6535 d 1 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1755 6540 d 10 h decky /boot/trunk/arch/ppc32/loader/ read macio address from PCI OFW entry  
1620 6554 d 5 h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1146 6619 d 7 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		  
1130 6628 d 4 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 6635 d 10 h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)		  
1058 6636 d 3 h decky /boot/trunk/arch/ppc32/loader/ relocate kernel in real mode  
964 6638 d 13 h decky /boot/trunk/arch/ppc32/loader/ ofw code cleanup
get memory map from ofw		  
956 6639 d 2 h decky /boot/trunk/arch/ppc32/loader/ relocate ppc32 kernel above 2 GB  
953 6639 d 4 h decky /boot/trunk/arch/ppc32/loader/ cleanup and extend OFW code  
885 6654 d 10 h decky /boot/trunk/ move ppc32 boot loader to /boot tree
