478dc9887e PPC: Preliminary untested boot support for Common Firmware Environment
CFE is used in the upcoming Amiga X-1000 dualcore PPC board.
* Largely inspired by the OF and U-Boot code.
* Still largely stubbed out.
* The loader builds but I don't have a machine to test it. Anyone interested?

d230708bcf * Expand kernel_args addresses ranges size, 8 is somewhat too small, leading
to a panic at boot.
* Make the panic message more explicit when there is no more room left.

This should hopefully fix #7869.

8837310ce7 * Slightly alter the semantics of the input gathering function to take the
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.

d2b49a0031 * Implement support for user input of additional safe mode options that
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.

d40a935560 Boot loader (x86 mmu.cpp):
* Made the page table allocation more flexible. Got rid of sMaxVirtualAddress
  and added new virtual_end address to the architecture specific kernel args.
* Increased the virtual space we reserve for the kernel to 16 MB. That
  should suffice for quite a while. The previous 2 MB were too tight when
  building the kernel with debug info.
* mmu_init(): The way we were translating the BIOS' extended memory map to
  our physical ranges arrays was broken. Small gaps between usable memory
  ranges would be ignored and instead marked allocated. This worked fine for
  the boot loader and during the early kernel initialization, but after the
  VM has been fully set up it frees all physical ranges that have not been
  claimed otherwise. So those ranges could be entered into the free pages
  list and would be used later. This could possibly cause all kinds of weird
  problems, probably including ACPI issues. Now we add only the actually
  usable ranges to our list.

Kernel:
* vm_page_init(): The pages of the ranges between the usable physical memory
  ranges are now marked PAGE_STATE_UNUSED, the allocated ranges
  PAGE_STATE_WIRED.
* unmap_and_free_physical_pages(): Don't free pages marked as unused.

858a20cab8 Patch by Vincent Duvert:
Remove the 4 cores limit at boot, and fix the allocator to handle 8 cores.
There are still performance problems, but this allows booting with 8 cores.
WARNING: since this changes x86 platform kernel args, you really don't want to update haiku_loader and kernel_x86 separately!

01c8294cc7 [ARM]
- 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).

9e8dc2a9bb [Sorry, couldn't split this one up any further.]
* Images preloaded by the boot loader had to be modules to be of any use
  to the kernel. Extended the mechanism so that any images not accepted
  by the module code would later be tried to be added as drivers by the
  devfs. This is a little hacky ATM, since the devfs manages the drivers
  using a hash map keyed by the drivers inode ID, which those drivers
  obviously don't have.
* The devfs emulates read_pages() using read(), if the device driver
  doesn't implement the former (all old-style drivers), thus making it
  possible to BFS, which uses the file cache which in turn requires
  read_pages(), on the device. write_pages() emulation is still missing.
* Replaced the kernel_args::boot_disk structure by a KMessage, which can
  more flexibly be extended and deals more gracefully with
  arbitrarily-size data. The disk_identifier structure still exists,
  though. It is added as message field in cases where needed (non net
  boot). Moved the boot_drive_number field of the bios_ia32 platform
  specific args into the message.
* Made the stage 1 PXE boot loader superfluous. Moved the relevant
  initialization code into the stage 2 loader, which can now be loaded
  directly via PXE.
* The PXE boot loader does now download a boot tgz archive via TFTP. It
  does no longer use the RemoteDisk protocol (it could actually be
  removed from the boot loader). It also parses the DHCP options in the
  DHCPACK packet provided by PXE and extracts the root path to be
  mounted by the kernel.
* Reorganized the boot volume search in the kernel (vfs_boot.cpp) and
  added support for network boot. In this case the net stack is
  initialized and the network interface the boot loader used is brought
  up and configured. Since NBD and RemoteDisk are our only options for
  net boot (and those aren't really configurable dynamically) ATM, the
  the boot device is found automatically by the disk device manager.

Booting via PXE does work to some degree now. The most grievous problem
is that loading certain drivers or kernel modules (or related activity)
causes a reboot (likely a triple fault, though one wonders where our
double fault handler is on vacation). Namely the keyboard and mouse input
server add-ons need to be deactivated as well as the media server.
A smaller problem is the net server, which apparently tries to
(re-)configure the network interface we're using to boot, which
obviously doesn't work out that well. So, if all this stuff is disabled
Haiku does fully boot, when using the RemoteDisk protocol (not being
able to use keyboard or mouse doesn't make this a particular fascinating
experience, though ;-)). I had no luck with NBD -- it seemed to have
protocol problems with the servers I tried.

ba61df6d0b Beginnings of APM support: we now connect to the APM BIOS in 32 bit protected mode.
We don't do anything with it yet, though, so the BIOS will probably ignore us since
we are supposed to poll for events.

e55e1a0e66 Implemented the PPC specific RTC support. We search for an "rtc"
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. :-/

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.

c83d9dad1c * platform_allocate_region() has a new boolean parameter "exactAddress"
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.

840ed4b067 Added a dummy member of the platform_kernel_args structure: obviously, the
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.
