Re: [GITGRUB] Support new object format for powerpc-ieee1275

[Bean]

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.
