* platform_allocate_elf_region() is removed, it is implemented in platform-
independent code now (ELF*Class::AllocateRegion). For ELF64 it is now
assumed that 64-bit addresses are mapped in the loader's 32-bit address space
as (address - KERNEL_BASE_64BIT + KERNEL_BASE).
* mapped_delta field from preloaded_*_image removed, now handled compile-time
using the ELF*Class::Map method.
* Also link the kernel with -z max-page-size=0x1000, removes the need for
2MB alignment on the data segment (not going to map the kernel with large
pages for the time being).
The ELF loader now uses a new platform function, platform_allocate_elf_region,
which returns 2 addresses: the real load address and an address where the
region is mapped in the loader's address space. All of the ELF loading code
has been changed to access the load region through the mapped address rather
than the addresses contained in the ELF image. The ELF64 version of
platform_allocate_elf_region on x86 uses the existing MMU code, which maps
everything at 0x80000000, but returns the correct 64-bit address. The long
mode switch code will just set up the 64-bit address space with everything
remapped at the correct address.
its size.
* Added "Display current boot loader log" item to the "Debug Options" boot
loader menu. It displays what the boot loader has logged so far. Might be
interesting for early boot issues when serial debugging is not possible.

menu item it's associated with rather than an input string. This allows it
to calculate the position to start the input at, as well as the correct
line to place it on. The previous solution always put the input at the
center line, which happened to be the right place by happy coincidence
unless one also had the menu items for viewing/saving the debug syslog
present.
* Implement input buffer scrolling, and consequently lift the previous size
limit on user input (it is now only limited by the size of the passed in
buffer).
* Implement parsing of the input buffer to allow it to handle comma-separated
options. Thus, one can now input things like "disable_smp true, serial_debug_output false"
and it will be handled properly.

aren't otherwise exposed via the safe mode menus. The option can be
found under the debug options menu, where additional settings can be
added one at a time with the same syntax used in kernel settings files
(i.e. disable_acpi on).
Scrolling of the input buffer is not yet supported (will implement that
soon), so currently the input is clamped to the size of one line. This
shouldn't be a problem for our current set of options though.

information to identify the boot volume - if we want to be able to map all BIOS
drive IDs to the disks in the system, we need to do this always, though.
* Forgot to commit the updated disk_identifier.h in the last commit...
* Removed the unused dumpBlock() function from devices.cpp.

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.

"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).
