3823 5594 d 10 h decky /trunk/boot/arch/sparc64/loader/ correct memory mapping for machines with physical memory displacement
this fixes booting on machines whose physical memory does not start at 0		  
3808 5601 d 8 h decky /trunk/ salvage duplicate configuration option  
3678 5647 d 2 h rimsky /trunk/boot/ Initialize the color palette for the 8-bit color depth on sparc64 framebuffers.  
3672 5648 d 5 h jermar /trunk/ Merge sparc branch to trunk.  
3408 5730 d 13 h jermar /trunk/boot/arch/sparc64/loader/ Use memmove() instead of memcpy() to copy the ramdisk image in the sparc64 loader.  
3399 5731 d 11 h jermar /trunk/boot/arch/sparc64/ Support for ramdisks external to image.boot on sparc64.

The sparc64 port can now boot from a ramdisk which is not part of image.boot.
This allows us to use larger ramdisks with SILO.		  
3388 5738 d 4 h jermar /trunk/boot/arch/sparc64/loader/ Be aware of the ramdisk passed by SILO.  
2250 6248 d 5 h jermar /trunk/boot/ Fix ticket #31.  
2071 6336 d 5 h jermar /trunk/ (c) versus (C)  
1997 6390 d 6 h decky /trunk/ add version to init and boot loader  
1979 6397 d 4 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1978 6397 d 5 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.		  
1977 6398 d 2 h jermar /trunk/ Fix bad indentation in ofw.c

sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.		  
1972 6409 d 12 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1899 6449 d 12 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		  
1897 6452 d 12 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6453 d 4 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.		  
1894 6456 d 3 h jermar /trunk/ Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations

More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree

sparc64 boot:
- pass OFW device tree root node pointer to kernel		  
1881 6463 d 12 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.		  
1837 6502 d 17 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
