2511 6278 d 2 h vana /trunk/ IA64 loader (based on sparc loader)  
2479 6356 d 8 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2438 6379 d 1 h decky /trunk/ update for new compiler configuration scheme  
2185 6434 d 9 h decky /trunk/ rename ipcc to tester  
2160 6442 d 3 h decky /trunk/boot/arch/ remove duplicate dependency  
2071 6513 d 1 h jermar /trunk/ (c) versus (C)  
1997 6567 d 2 h decky /trunk/ add version to init and boot loader  
1989 6570 d 7 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6573 d 9 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.		  
1894 6632 d 23 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		  
1893 6633 d 3 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6640 d 9 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.		  
1864 6648 d 22 h jermar /trunk/ sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64.		  
1789 6701 d 7 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 6703 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1771 6711 d 2 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).		  
1764 6719 d 0 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1763 6719 d 1 h jermar /boot/trunk/ Cleanup in the boot infrastructure.
This commit tries to separate generic stuff from mips32 specific stuff.
Other architectures will follow.		  
1747 6726 d 0 h decky /boot/trunk/ mips32 binary format choice  
1685 6734 d 11 h decky /boot/trunk/arch/mips32/ mips piggybacker
