3672 5624 d 1 h jermar /trunk/ Merge sparc branch to trunk.  
3274 5741 d 5 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.		  
3146 5797 d 10 h jermar /trunk/boot/arch/sparc64/loader/ Don't make any assumptions about the contents of the I-cache in sparc64
loader and before passing control to the kernel, invalidate the I-cache.		  
3144 5798 d 0 h jermar /trunk/boot/arch/sparc64/loader/ Issue a sparc64 write barrier before passing control from the loader to
the kernel.		  
2071 6312 d 0 h jermar /trunk/ (c) versus (C)  
1978 6373 d 0 h jermar /trunk/ sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.		  
1899 6425 d 8 h jermar /trunk/ sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree		  
1791 6500 d 1 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 6500 d 3 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.		  
1787 6502 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6503 d 0 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.		  
1778 6509 d 6 h jermar /boot/trunk/arch/sparc64/ sparc64 is now booted by HelenOS boot loader.  
1773 6509 d 22 h jermar /boot/trunk/arch/sparc64/loader/ Work on sparc64 boot loader (still inactive).  
1771 6510 d 1 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1685 6533 d 10 h decky /boot/trunk/arch/mips32/ mips piggybacker  
1018 6620 d 6 h decky /boot/trunk/ boot loader for msim
