- don't clobber the parameter regs in the entry point,
- fix entry point address for netbsd loader emulation,
- added a gUImage global to point to the uimage blob with the tgz,
- added tgz info to platform stage2 args,
- add simple uimage support, just dumps the header and gets the nth blob in the image, (seems we have a bug in the math code, some infos don't print),
- made devices.cpp use them to publish the MemoryDisk,
- add an haiku_loader_nbsd.ub target which puts both the loader and kernel_arm for now (need to replace with the tgz).

- cleanup,
- moved the startup asm code to u-boot/arch/arm/shell.S
- added netbsd loader entry point,
- store the invocation type (0: standalone, 1: netbsd),
- store the global data in a variable,
- added some debug code to see what U-Boot gives us.

- consolidate board specific definitions into build/jam/board/*/BoardSetup to avoid duplicating address values everywhere,
- add various addresses, boot script, custom C/C++ flags and SD card definition,
- not sure BoardSetup is included at the best place though,
- replaced board-specific ldscript with passing the loader address directly to LD from BoardSetup,
- added haiku.mmc target which generates an mmc/SD card image with a FAT partition with the files needed to boot for the board, should later be integrated with haiku.image with the BFS partition offset passed to bfs_shell, requires apt:sfdisk,mtools on GNU/Linux,
- added some more rules, one to build a script for the SD image,
- fake a NetBSD loader for now, U-Boot doesn't know haiku, and we'll need a way to pass the tgz image and RAM size, we'll either use standlone way (usual C argv[]) or the NetBSD args,
- style fixes,
- 80 cols, /me pets Ingo.

Add rule to handle uimage, and board-specific stuff to handle load addresses. Need to fix them, u-boot doesn't like loading the file with the header where the header says it should go, must copy to a different address.

Include board-specific file from the u-boot ldscript, to allow linking to different load addresses.

- use board_config defines in uart.c.

- added some multiboot support code:
- dump some of the passed info,
- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)

ROUNDUP to use '*' and '/' -- the compiler will optimize that for powers of
two anyway and this implementation works for other numbers as well.
* The thread::fault_handler use in C[++] code was broken with gcc 4. At least
when other functions were invoked. Trying to trick the compiler wasn't a
particularly good idea anyway, since the next compiler version could break
the trick again. So the general policy is to use the fault handlers only in
assembly code where we have full control. Changed that for x86 (save for the
vm86 mode, which has a similar mechanism), but not for the other
architectures.
* Introduced fault_handler, fault_handler_stack_pointer, and fault_jump_buffer
fields in the cpu_ent structure, which must be used instead of
thread::fault_handler in the kernel debugger. Consequently user_memcpy() must
not be used in the kernel debugger either. Introduced a debug_memcpy()
instead.
* Introduced debug_call_with_fault_handler() function which calls a function
in a setjmp() and fault handler context. The architecture specific backend
arch_debug_call_with_fault_handler() has only been implemented for x86 yet.
* Introduced debug_is_kernel_memory_accessible() for use in the kernel
debugger. It determines whether a range of memory can be accessed in the
way specified. The architecture specific back end
arch_vm_translation_map_is_kernel_page_accessible() has only been implemented
for x86 yet.
* Added arch_debug_unset_current_thread() (only implemented for x86) to unset
the current thread pointer in the kernel debugger. When entering the kernel
debugger we do some basic sanity checks of the currently set thread structure
and unset it, if they fail. This allows certain commands (most importantly
the stack trace command) to avoid accessing the thread structure.
* x86: When handling a double fault, we do now install a special handler for
page faults. This allows us to gracefully catch faulting commands, even if
e.g. the thread structure is toast.
We are now in much better shape to deal with double faults. Hopefully avoiding
the triple faults that some people have been experiencing on their hardware
and ideally even allowing to use the kernel debugger normally.

- stubbed out arch_cpu_init_percpu(),
- make atomic ops declarations extern "C",
- move calls to [i]sync inside the asm code that needs it.

Based on a patch from Dustin Howett, reworked, and help from Vladimir 'phcoder' Serbinenko.
- used defines for clarity, the rest of teh code could make use of them too...
- added a gMultiBootInfo pointer to the passed args, to let C code handle it instead of faking the boot drive ID,
- conditionalized the copy back, maybe we can get rid of it when QEMU handles our default load address correctly,
- added video mode info to ask for 1024x768 but QEMU ignores it anyway, and we might need to show the menu, so it's disabled.

* Changed the boot loader to have architecture dependent partition/file system
support. Amiga/Apple partitions, and the AmigaFFS file system are now only
supported on PPC, while EFI GPT, and the FAT file system is now only supported
on x86.

KPartition::CreateChild(). CreateChild() calls AddChild(), which publishes
the new partition, though at that point offset and size were not set, so that
the published devices would not be usable.

* A CHS read error would previously be hidden by a successful disk system reset.
Not that it matters much because it'd have resulted in a non-booting system
anyway.
* Add some more debug output, minor cleanup.

- move gBoot* out of the boot sector,
- fix the FAT params to actually indicate 1.44kB floppy,
- fix the FloppyDrive class to also use 18 sectors/track, so now tarfs won't get data from start of disk when on the middle.

- loop on Floprd() alternating sides every sect/track, currently hardcoded from the FAT bootblock as probing like the NetBSD loader asserts ARAnyM,
- print a dot / sector read in the great tradition of bootloaders,
- set gBootedFromImage correctly,
- fix the script, make it jam later on.

and another one silently fails the read, previously preventing CD-boot on both.

* Made the TimeZoneView less error prone, and also actually use Haiku code (the
previous check didn't work since it used #if, not #ifdef).
* Also took the liberty to rename our boot loader to haiku_loader, since I had
to update the nasm binary anyway. Updated the assembly sources to nasm 2.0.
* I haven't found where the synth location in the MIDI code is specified,
though.
* Also, NetBootArchive, and FloppyBootImage haven't been updated yet. Will do
so next.
* Some optional packages still put their license to beos/etc/licenses. I didn't
update them yet, as we'll probably do so anyway at some point. Also, I think
we might want to introduce a common/data/licenses instead for those.
* If you encounter any problems, please tell!

This allows to have the first item selected when entering a menu, since still
pressing space would not enter it unintentionally anymore, in case it's a sub-
menu again. Even though it makes some sense to have "Continue booting" selected
by default, it somehow feels more natural to have the first item always selected
instead. Thanks!
