1792 6520 d 21 h jermar /trunk/ Move functionality of tlb_arch_init() to take_over_tlb_and_tt().
Call take_over_tlb_and_tt() very early after the kernel starts
executing.		  
1790 6521 d 2 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 6521 d 4 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 6523 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6523 d 22 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.		  
1777 6530 d 4 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
895 6656 d 23 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.		  
867 6662 d 4 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
847 6667 d 1 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6667 d 2 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
534 6742 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6742 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
529 6744 d 3 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add dummy trap tables.		  
501 6754 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
426 6777 d 5 h jermar /SPARTAN/trunk/ sparc64 work.
Add context_save(), context_set() and context_restore().
Remove putchar() definition from ofw.c.
Add sparc64 putchar().
Add ppc32 putchar() (i.e. the original ofw.c putchar()).
Make arg.h use the builtin va_* constructs.		  
424 6778 d 6 h jermar /SPARTAN/trunk/ sparc64 work.
Link kernel with load address 0x4000.
Add fragment of Linux image header to force SILO to always load the kernel at 0x4000.
Adjust ofw.h and ofw.c to work also on sparc64.		  
420 6781 d 21 h jermar /SPARTAN/trunk/arch/sparc64/ Small sparc64 changes.
Start native boot loader.		  
418 6784 d 23 h jermar /SPARTAN/trunk/ sparc64 infrastructure.
