1824 6540 d 2 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6540 d 3 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6540 d 8 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.

1800 6555 d 19 h decky /trunk/boot/arch/ppc64/loader/ sync ppc64 with ppc32  
1799 6555 d 19 h decky /trunk/boot/arch/ppc32/loader/ fix typo  
1798 6555 d 19 h decky /trunk/uspace/ make uspace compile for ppc64  
1797 6555 d 19 h decky /trunk/uspace/ dummy Sparc64 uspace support (it just compiles)  
1796 6555 d 19 h decky /trunk/boot/tools/ia64/ new place for vmaxlma  
1795 6555 d 19 h decky /trunk/contrib/ remove orphaned directory  
1794 6555 d 19 h decky /trunk/ move contrib from kernel/ to /
update Sparc64 toolchain to use Binutils 2.17 (neeeded for linking uspace)		  
1793 6558 d 7 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.		  
1792 6558 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.		  
1791 6558 d 23 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 6559 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 6559 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.
