1791 6689 d 5 h jermar /trunk/boot/arch/sparc64/loader/ Switch to identically mapped stack during boot.
Put stack related and register related macros to dedicated
header files.		  
1790 6689 d 8 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.		  
1789 6689 d 10 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 6691 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6692 d 4 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.		  
1782 6697 d 11 h jermar /boot/trunk/ Fix ofw.c to support map and translate methods even on 64-bit platforms.  
1779 6698 d 8 h jermar /boot/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1778 6698 d 10 h jermar /boot/trunk/arch/sparc64/ sparc64 is now booted by HelenOS boot loader.  
1773 6699 d 3 h jermar /boot/trunk/arch/sparc64/loader/ Work on sparc64 boot loader (still inactive).  
1771 6699 d 5 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 6707 d 4 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1763 6707 d 4 h jermar /boot/trunk/ Cleanup in the boot infrastructure.
This commit tries to separate generic stuff from mips32 specific stuff.
Other architectures will follow.		  
1748 6714 d 4 h decky /boot/trunk/arch/mips32/loader/ bugfix  
1747 6714 d 4 h decky /boot/trunk/ mips32 binary format choice  
1744 6714 d 4 h decky /boot/trunk/arch/mips32/loader/ use stack in unmapped segment  
1685 6722 d 14 h decky /boot/trunk/arch/mips32/ mips piggybacker  
1018 6809 d 10 h decky /boot/trunk/ boot loader for msim
