2078 6321 d 4 h jermar /trunk/kernel/arch/sparc64/src/ When invalidating entire TLBs on sparc64, make sure to also invalidate any (locked) global entries.
This fixes Ticket #21.
Fix a comment in start.S stating that the kernel installs a global entry for itself. All entries installed by the kernel
are local to some memory context.		  
2071 6325 d 0 h jermar /trunk/ (c) versus (C)  
2058 6351 d 9 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2049 6356 d 8 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2009 6368 d 23 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6371 d 0 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2001 6374 d 22 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6381 d 2 h jermar /trunk/kernel/ Add option to compile the sparc64 kernel without the TTE_CV bit support.
The bit is not used by default now.
Enabling it may theoretically lead to physical memory inconsistencies until code that
mitigates the problem is written.		  
1982 6385 d 8 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.		  
1978 6386 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.		  
1975 6395 d 23 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1954 6407 d 23 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1917 6425 d 1 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.		  
1906 6435 d 3 h jermar /trunk/ Small improvements in sparc64.  
1905 6435 d 10 h jermar /trunk/kernel/arch/sparc64/src/ Small fixes.
The sparc64 kernel now compiles again even if not compiled with SMP support.		  
1903 6437 d 0 h jermar /trunk/ SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.		  
1900 6438 d 7 h jermar /trunk/kernel/arch/sparc64/src/ Block the secondary processors after they setup kernel mapping in ITLB and DTLB and
switch to kernel trap table.		  
1899 6438 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		  
1887 6450 d 7 h jermar /trunk/kernel/arch/sparc64/ When creating TLB mapping for the sparc64 kernel, enable CV (cacheable virtually) bit.
Also install locked mappings only in context 0.		  
1881 6452 d 8 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.
