f812331857 PPC: Add a platform field to the arch_kernel_args
* We need to know which platform we are booted from

716a16ce61 * Find out a few interesting information about the system (like CPU,
bus, and time base frequency) in the PPC boot loader, and propagate
  them to the kernel via kernel_args.
* Now we use the correct time base frequency for timer calculations.
* Implemented PPC specific system info stuff. Added a few PPC CPU
  types to <OS.h>.

a1bcf2c880 * The OF memory management callback is now set in arch_mmu_init().
According to the spec we need to set it before taking over the MMU,
  but we can't call it before arch_mmu_init(), since we need the OF
  to allocate the page table. So we do it after we have allocated
  the new page table.
* Added PPC specific kernel_args: The virtual address ranges we want
  to keep in the kernel. We fill that in with the translations we
  find when initializing the MMU stuff. We remove the memory the
  boot loader occupies from those. Besides the stack for the boot
  loader only the OF stuff remains.
* arch_mmu_allocate() now starts to search at KERNEL_BASE for a free
  virtual address when no particular address is requested. This saves
  us further trouble in the kernel, since those allocations would
  need to be remapped otherwise.
