4348 5772 d 14 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
3403 6001 d 12 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
2927 6123 d 13 h decky /branches/dynload/ added dynload branch  
2071 6607 d 2 h jermar /trunk/ (c) versus (C)  
1972 6680 d 9 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1917 6707 d 4 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 6717 d 5 h jermar /trunk/ Small improvements in sparc64.  
1792 6795 d 1 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 6795 d 3 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.		  
1789 6795 d 8 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 6797 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1783 6798 d 2 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.		  
1773 6805 d 0 h jermar /boot/trunk/arch/sparc64/loader/ Work on sparc64 boot loader (still inactive).  
1771 6805 d 3 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1744 6820 d 2 h decky /boot/trunk/arch/mips32/loader/ use stack in unmapped segment  
1685 6828 d 12 h decky /boot/trunk/arch/mips32/ mips piggybacker  
1018 6915 d 8 h decky /boot/trunk/ boot loader for msim
