14cfccd011 U-Boot: add a 'physical' arg to fdt_get_device_reg()
If false, try to use the virtual-reg property first.

c6a4fee579 loader/u-boot: Use FDT serial info to create uart
* drop my fdt tests
* we have to call fdt parsing code *after* cpu_init (why?)
* pass fdt pointer to all FDT support calls to avoid confusion
  once we get into the kernel land
* look for PL011 compatible uart and use it
* Add some saftey checks to serial putc code to avoid null*
* fdt_node_check_compatible returns 0 on success not 1
* fdt_get_device_reg needs to add the SOC base to the result
* fdt_get_device_reg might need to add the second range cell
  instead of reg?

f121867b87 arm/fdt: Initial reorg of fdt support code
* Makes FDT support code useable by everyone
  without all of the externs
* Further movement to be non-u-boot centic
  may still happen.

5dfa763cb1 OF: Make sure the of_region templatized struct is packed
At least when building for sam460ex, it ended up being 16bytes large...

d24ddec4e4 * Move platform support.cpp into less generic of_support.cpp
* Add header file to support of_support.cpp
* Add support functions to obtain address and size cell lengths
* Small style cleanups
* Add support for G5 PowerPC cpus...
* Refactor memory region code to be aware of 64-bit OF addresses.
  As-is the boot loader wouldn't start on G5 systems because
  OpenFirmware memory base addresses are stored as two 32-bit
  unsigned int 'cells' vs one 32-bit unsigned int 'cell' on G3/G4.
  I removed the static struct and replaced it with a template
  and pass uint32 or uint64 depending on the address cell size.
  Thanks for the idea DeadYak!

04ec719a70 Convert line endings to LF
In r33670 the svn:eol-style property was dropped, which took care of
locally converting the line endings to the user's native style.
While most files use Unix-style LF line endings, some files have
Windows-style CR LF line endings.

Assure that the following r37262 directories use Unix-style line endings:

src/system/boot/
src/system/boot/arch/
src/system/boot/arch/ppc/
src/system/boot/loader/
src/system/boot/loader/net/
src/system/boot/platform/
src/system/boot/platform/openfirmware/
src/system/boot/platform/openfirmware/arch/
src/system/boot/platform/openfirmware/arch/ppc/
src/system/kernel/
src/system/kernel/arch/
src/system/kernel/arch/ppc/
src/system/kernel/platform/
src/system/kernel/platform/openfirmware/
headers/private/kernel/
headers/private/kernel/arch/
headers/private/kernel/arch/ppc/
headers/private/kernel/platform/
headers/private/kernel/platform/openfirmware/
headers/private/kernel/boot/
headers/private/kernel/boot/net/
headers/private/kernel/boot/platform/
headers/private/kernel/boot/platform/openfirmware/

This avoids patches containing irrelevant lines unintentionally converted.

No functional changes.

d4dcbf95f6 - Fix build.
- make system_time() return something sensible until platform code works.

86cb5b45da - Move MFP freq to a separate header
- initialize the time_base_frequency kernel arg (should be done in the bootloader though...). We will use MFP timer to support system_time(). At least try to.

906b28a9ac Added some PPC support to the PCI bus manager. We scan the Open Firmware
device tree for PCI controllers and make them known to the bus manager,
if we know how to talk with them. ATM we support only the UniNorth chip,
which can be found in G4 Macs (code ported from FreeBSD).
As far as I can judge it, all attached devices are identified correctly
on all three host bridges of my Mac mini.

f602da2b72 * Turned the kernel platform support from a library into an object.
* Moved the Open Firmware function platform_get_next_device() from
  the boot loader into the kernel (renamed to of_get_next_device()).

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.
