* make runtime_loader a dynammically linked object
* add kernel support for loading user images that need to be relocated
* load runtime_loader at random address
* Raspberry Pi is broken now after
the other recent arm work... needs
more investigation.
* Comment out stage2 header as it
links to headers with c++ code.
Need to verify entry.s can call
c++ code (I think it's mangled to
the assembly or something)
* Fix naming of code entry to match
other arm code.
* Added x86_64 linker script and relocation code.
* Some 64-bit safety fixes to the heap code.
* Added runtime_loader, libroot and bash to the x86_64 image. The boot
script will be launched, but will panic shortly after because fork
is broken.
* 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).
* Based on the x86 one, changes made to match the default GCC x86_64 linker
script and correct kernel load address added.
* Not tested yet as the kernel doesn't fully compile.
* x86_64 is using the existing *_ia32 boot platforms.
* Special flags are required when compiling the loader to get GCC to compile
32-bit code. This adds a new set of rules for compiling boot code rather
than using the kernel rules, which compile using the necessary flags.
* Some x86_64 private headers have been stubbed by #include'ing the x86
versions. These will be replaced later.
* Add some missing stuff, be more exact with
stack and fill with 0xBEBEBEBE
* Ensure .init_array is called with .ctors to ensure
static constructors are called.
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?
the state of the ARM port to booting all the way up to the idle thread again.
However, will still need to investigate why we need the PHDRS magic, likely due to improper
setup of the ARM toolchain. If anyone has ideas, please let me know!

* Fix a typo in the comments: unintialized -> uninitialized.
Thanks a lot!

* Fix duplicate assignment which is probably a merging artifact.
This patch was also a requirement for a working PPC KDL prompt. I didn't
apply the patches in order... Thanks a lot!

This seems to work around the dynamic segment having a huge file size in headers, it must also be in the data segment...

Don't forget the ELF header else we end up loading at 0x7fff8000...

Use the same trick as for m68k (r26536) to get separate text & data segments for the kernel, though this should really not be needed.

Add unwind symbols to the kernel too... not sure it goes here though.

Move the unwind data out of the bss section, it broke bss init which ended up erasing real data and making dprintf do weird things...

Missed this one in previous commit: remove board.ld include as we now give LD the address directly.

- consolidate board specific definitions into build/jam/board/*/BoardSetup to avoid duplicating address values everywhere,
- add various addresses, boot script, custom C/C++ flags and SD card definition,
- not sure BoardSetup is included at the best place though,
- replaced board-specific ldscript with passing the loader address directly to LD from BoardSetup,
- added haiku.mmc target which generates an mmc/SD card image with a FAT partition with the files needed to boot for the board, should later be integrated with haiku.image with the BFS partition offset passed to bfs_shell, requires apt:sfdisk,mtools on GNU/Linux,
- added some more rules, one to build a script for the SD image,
- fake a NetBSD loader for now, U-Boot doesn't know haiku, and we'll need a way to pass the tgz image and RAM size, we'll either use standlone way (usual C argv[]) or the NetBSD args,
- style fixes,
- 80 cols, /me pets Ingo.

Temporary (?) solution to linking the loader: generate symbols needed by the unwinding code, which should actually not be used since we disable exceptions...
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32239 a95241bf-73f2-0310-859d-f6bbb57e9c96
Include board-specific file from the u-boot ldscript, to allow linking to different load addresses.

This makes the kernel loadable by the bootloader, which does load it, and all the modules \o/
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26558 a95241bf-73f2-0310-859d-f6bbb57e9c96
This allowes to actually execute the boot loader now.
Need to use Ingo's remote_disk_server now for booting.
