device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
compiler/linker flags specifying the kind of position independence
the kernel shall have. For x86 we had and still have -fno-pic, but the
PPC kernel has -fPIE (position independent executable) now, as we
need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
code from the kernel ELF loader. Almost completely rewrote the PPC
specific relocation code, though. It's more correct and more complete now
(some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
(made OF device iteration a bit more flexible on the way -- the search
can be restricted to subtree). Furthermore we really enter the kernel...
(Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
called by acquire_spinlock()). kprintf() works, though.

specifying whether only the exact supplied address is acceptable. If
false, the address is considered a hint only. It will be picked, if
available, otherwise a greater address is tried to be acquired, and
as last resort any address. This feature is only implemented for PPC.
It is needed since the preferred kernel text base address 0x80000000
might not be available (and actually isn't on my Mac mini).
* Fixed a bug in the PPC memory management code:
is_{virtual,physical}_allocated() were checking whether the given
range was completely contained by an existing range instead of
checking for intersection. As a consequence we could (and did) allocate
a range intersecting with already allocated ranges. The kernel segment
thus overwrote OF memory for instance.
* The ELF loader makes sure that it got both text and data segment of
the image to be loaded.
The PPC boot loader successfully loads kernel and modules now. Next
comes the hard part, I'm afraid.

IP, and UDP, as well as a home brewn UDP based protocol, "remote disk",
which provides random access to a single remote file/device. The Open
Firmware flavored boot loader automatically initializes the net stack,
searches for a remote disk, and tries to boot from it, if the boot
device is a network device (e.g. when loading the boot loader via
TFTP).
This is quite nice for developing with a two-machine setup, since one
doesn't even need to install Haiku on the test machine anymore, but can
serve it directly from the development machine. When the networking
support in the kernel is working, this method could even be used to
fully boot, not just for loading kernel and initial modules.

"booted_from_image" in the kernel_args' boot_disk structure.
Also, added fields "cd" and "user_selected".
A CHOICE_MENU menu can now have a choice text - this is automatically updated
as entries in the menu get selected.
The boot volume menu now has the initial choice text "CD-ROM or hard drive"
in case the boot loader was loaded from an image. The "Rescan volumes" item
is no longer selected by default (only if there was no boot volume found) - but
it's still functionless anyway.
The TAR fs will now appear as "Boot from CD-ROM" in the boot volume menu.

like floppy or CD boot.
This allows it to reduce the number of scans needed to identify the boot
partition - when booted from a real floppy, this speeds up the boot
process by a magnitude.
Also, the loader now has a fall back in case there were no "boot" links
on the disk - the current boot floppy script doesn't create them.
With these changes, I was able to boot into a HD based Haiku installation
from a floppy disk. It's not yet enough to boot from CD (as the boot
device selection is a bit too simplistic right now), but it will eventually
come next. Testing is a lot slower here, though, as neither qemu nor
Bochs support multi-session CDs (at least I have no idea how to get them
to do this).

The partition now also tracks if it refers to a partitioning system or not.

Removed the "str" field I have no idea what it could have been useful for.
Changed the frame buffer part of the kernel args - "already_mapped" is
no longer there, as it doesn't make a lot of sense.

kernel didn't count an empty structure, while the boot loader reserved
4 bytes for it - dunno why, a _PACKED everywhere didn't help; it's probably
a compile option issue.
To be on the safe side always, I've now added this dummy.

Changed the get_file_system() call to accept a Partition instead of just
a node.
Introduced the namespace boot to the public headers; I guess I should
put all classes in there (compilation of the intel partitioning system
fails without the namespace, because it defines a class Partition itself).
