4308 6225 d 4 h decky /trunk/boot/arch/ppc32/loader/ add support for alternate spelling of macio alias  
3829 6306 d 10 h decky /trunk/ use macio optionally  
3387 6452 d 16 h decky /trunk/ ppc32 updates  
2071 7049 d 7 h jermar /trunk/ (c) versus (C)  
1799 7234 d 3 h decky /trunk/boot/arch/ppc32/loader/ fix typo  
1789 7237 d 12 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 7239 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 7240 d 6 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.		  
1771 7247 d 7 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 7255 d 6 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1755 7260 d 15 h decky /boot/trunk/arch/ppc32/loader/ read macio address from PCI OFW entry  
1620 7274 d 10 h decky /boot/trunk/arch/ppc32/loader/ update boot loader API  
1146 7339 d 12 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 7348 d 9 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1075 7355 d 14 h decky /boot/trunk/arch/ppc32/loader/ relocate boot loader structures if needed
(allowing to boot on stupid OFW implementations)		  
1058 7356 d 8 h decky /boot/trunk/arch/ppc32/loader/ relocate kernel in real mode  
964 7358 d 18 h decky /boot/trunk/arch/ppc32/loader/ ofw code cleanup
get memory map from ofw		  
956 7359 d 7 h decky /boot/trunk/arch/ppc32/loader/ relocate ppc32 kernel above 2 GB  
953 7359 d 8 h decky /boot/trunk/arch/ppc32/loader/ cleanup and extend OFW code  
885 7374 d 15 h decky /boot/trunk/ move ppc32 boot loader to /boot tree
