[GITGRUB] Support new object format for powerpc-ieee1275

[Bean]

Hi,

Support new object format for powerpc-ieee1275 platform, I create the
image with cross compile in i386 environment, so that the elf
converter should be endianness safe.

There are still some problem, but they don't seems to be related to
the new object format, as it also exist in svn code. Claim memory
seems to fail, so the image halts pretty soon, tested with OpenBios
with qemu-ppc and ppc mac mini. And the calls to "output-device
output" in ofconsole would generate an exception, just comment it out
for now.

Hi,

Add support for OpenBIOS. it would detect OpenBIOS and add flags for
the OpenBIOS platform.

The problem with OpenBIOS:

/memory/available is present, but the value is different from olpc,
instead of start-size pair, it's four number consist of:

0 min_mem max_mem total_mem

The current mmap enumerator would generate incorrect data. This is
handled by setting the force claim flag so that it just claim memory
directly.

nextprop method is not implemented, this caused a infinite loop when
probing aliases, fixed by checking the return value.

With these, it's all right to boot into grub shell, but there are no
disk device, this is another unimplemented feature of OpenBIOS, as you
also can't list device in the openbios shell.

Hi,

Update:

Support ppc mach-o object file, now you can compile grub2
powerpc-ieee1275 in OSX.

As Xcode have included powerpc cross compiler, you don't need to
install extra software, just use the following configure command:

./configure --with-platform=ieee1275 --target=powerpc
TARGET_CC=powerpc-apple-darwin9-gcc-4.0.1

With this patch, new object format support is basically finished, now
you can compile the following targets in Windows, OSX and Linux:

Windows:
all i386 targets, x86_64 targets (needs mingw-w64)

OSX:
all i386, x86_64 and powerpc targets.

Linux:
all i386, x86_64 (needs multilib), and powerpc (need cross compiler) targets

Hi,

Update: fix a few endian and relocation issue, I can now build all
i386/x64_64/powerpc targets from x86/powerpc OSX Tiger/Leopard.

Note: when building on OSX, I recommend adding configure option
--disable-grub-fstest --disable-grub-emu --disable-mkfont. grub-fstest
can be built successfully, but OSX don't allow executing code from
stack, running grub-fstest would cause a segment fault. grub-emu can
be broken occasionally, and even if it's compiled ok, it has the same
problem as grub-fstest. grub-mkfont is currently broken on OSX.

Here are some information on configure parameter:

x86 OSX 10.5 (Leopard), Xcode 3.0, gcc 4.0
i386-pc:
./configure --with-platform=pc --disable-grub-fstest
--disable-grub-emu --disable-mkfont

x86_64-efi:
./configure --with-platform=efi  --target=x86_64 --disable-grub-fstest
--disable-grub-emu --disable-mkfont

powerpc-ieee1275:
./configure --with-platform=ieee1275  --target=powerpc
TARGET_CC=powerpc-apple-darwin9-gcc-4.0.1 --disable-grub-fstest
--disable-grub-emu --disable-mkfont

powerpc OSX 10.4 (Tiger), Xcode 2.5, gcc 4.0
i386-pc:
./configure --with-platform=pc --target=i386
TARGET_CC=i686-apple-darwin8-gcc-4.0.1 --disable-grub-fstest
--disable-grub-emu --disable-mkfont

x86_64-efi:
./configure --with-platform=efi  --target=x86_64
TARGET_CC=i686-apple-darwin8-gcc-4.0.1 --disable-grub-fstest
--disable-grub-emu --disable-mkfont

powerpc-ieee1275:
./configure --with-platform=ieee1275 --disable-grub-fstest
--disable-grub-emu --disable-mkfont

BTW, the default bison installed on OSX tiger would cause compile
error, install bison from macport and it would be ok.

zfsinfo branch

[Seth Goldberg]

Hi,

   Any chance I could convince you to merge that in with the nested partition 
and sunpc changes + the current trunk?  It would definitely make it easier for 
me to merge the changes into my workspace...

  Thanks,
