957a1b17eb * Introduced new build system variables
{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.

e07c1f2cc1 Now stores an inode number along with the other preloaded image data.

fa1ddc4f0e For debugging purposes, the boot loader is now able to load an additional
symbol table into memory and hand it over to the kernel.

6e062dd1b5 Added an ID field that connects the real kernel image with the preloaded image structure.

d07a6f89a0 Actually, elf_region already contains an area_id field...

c2c0779e26 Added two fields that ease the kernel initialization of the preloaded images.

b73b3e5a2d Changes for the ELF loader in the boot loader.
Removed the arch_mmu_alloc() function, added (empty) arch_mmu_free() function.
Added platform prototypes for allocating and freeing a region.
