3883 5602 d 3 h decky /trunk/boot/ simplify configuration  
3803 5625 d 5 h decky /trunk/ configuration system overhaul (requires newt)  
3523 5710 d 4 h decky /trunk/ finish mkfat.py
this drops build dependency on mtools
 
3491 5725 d 1 h jermar /trunk/boot/ Introduce a boot component configuration option CONFIG_RD_EXTERNAL.
Currently used by the sparc64 port. It says whether the ramdisk
is part of image.boot or a separate file.
 
3486 5731 d 9 h decky /trunk/ faster compilation using -pipe  
3462 5747 d 12 h svoboda /trunk/ Include trace on sparc64 ramdisk. Assorted fixes.  
3410 5753 d 9 h svoboda /trunk/ Introduce directories '/app' and '/srv' on ramdisk instead of '/sbin' to mirror source tree.  
3407 5753 d 11 h jermar /trunk/boot/arch/sparc64/loader/ Prevent gcc from generating FPU code for the sparc64 loader.  
3399 5754 d 9 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.
 
3368 5771 d 7 h decky /trunk/ configurable cross-compiler prefix (using CROSS_PREFIX)  
3349 5776 d 12 h jermar /trunk/ Enable bdsh in most of the architectures, remove cli and simplify init.  
3324 5783 d 6 h jermar /trunk/boot/arch/sparc64/loader/ Boot support for FAT16 on sparc64.  
3258 5789 d 6 h decky /trunk/boot/arch/ use less cryptic filenames  
3244 5793 d 2 h jermar /trunk/ Split mktmpfs.py to a TMPFS specific part and a HORD specific part. The latter
is moved to mkhord.py and can be reused for FAT16 images as well. mktmpfs.py and
mkfat.sh define the same interface now. Modify makefiles to use the modified
interface (e.g. do not pass alignment to either mktmpfs.py or mkfat.sh). FAT16
initrd image can be now loaded as initrd on amd64 and gets recognized as a
ramdisk image.
 
3222 5821 d 7 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3052 5856 d 9 h decky /trunk/boot/arch/ RAM disk / filesystem support  
3027 5860 d 9 h decky /trunk/boot/ finish unifying pack script  
3024 5861 d 7 h decky /trunk/boot/arch/ use unified pack script by arm32  
2649 6025 d 16 h jermar /trunk/boot/arch/ Enable tmpfs in arm32, ia32xen, ia64, ppc32, ppc64 and sparc64.  
2551 6105 d 6 h cejka /trunk/ DevMap, VFS and FAT added to boot images for all architectures.  
2511 6124 d 4 h vana /trunk/ IA64 loader (based on sparc loader)  
2479 6202 d 10 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2438 6225 d 2 h decky /trunk/ update for new compiler configuration scheme  
2185 6280 d 11 h decky /trunk/ rename ipcc to tester  
2160 6288 d 4 h decky /trunk/boot/arch/ remove duplicate dependency  
2071 6359 d 3 h jermar /trunk/ (c) versus (C)  
1997 6413 d 4 h decky /trunk/ add version to init and boot loader  
1989 6416 d 9 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6419 d 11 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 6479 d 1 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 6479 d 4 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6486 d 10 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 6495 d 0 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 6547 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 6549 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1771 6557 d 4 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).
 
1764 6565 d 2 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1763 6565 d 2 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 6572 d 2 h decky /boot/trunk/ mips32 binary format choice  
1685 6580 d 12 h decky /boot/trunk/arch/mips32/ mips piggybacker
