This patch originally started as a fix for PPC, in that the NVRAM initialiser wasn't been run on startup (this is why printenv
on PPC always showed much much less than on SPARC). However, it also showed up some inconsistent logic for boot device
selection, which must also happen *before* boot is called in order for load to work correctly. With this patch applied, bootpath
and bootargs are set from boot-device and boot-args respectively on startup for SPARC32, SPARC64 and PPC.
Note: there is a small chance SPARC32 may break on some images - please let me know if it does.

used by sys_info and so these are also renamed to elf_info.c and linuxbios_info.c for clarity.

This adds a better support of Apple BootX script.
However, "init-program" and "go" are always missing to be able to really boot with BootX.

CHRP boot method.
It finds the CHRP bootscript using the file attribute 'tbxi' and
the blessed directory.
This method allows to boot easily Fedora (the bitness detection is done
by the script and yaboot is called with the according yaboot.conf) but
openSUSE is broken (you have to use "boot cd:,\suseboot\yaboot")
Debian works well (as usual...).
The openSUSE needs the missing forth words: "load" and "go".
The MacOS bootloader (BootX) is also loaded automatically but forth
script is too complex to be executed correctly.

It is needed to boot Fedora-10 as we must specify the path to the yaboot.conf.
To boot Fedora:
boot cd: conf=cd:,\ppc\ppc32\yaboot.conf
so "bootpath" is "cd:", and "bootargs" is "conf=cd:,\ppc\ppc32\yaboot.conf"

To keep compatibility with yaboot (tested with debian install CD),
put in bootpath a fully qualified path (<device>:<partition>,<filename>)

<boot-script>boot &device;:1,\suseboot\yaboot.ibm</boot-script>.
This would evaluate to boot cd:0,1\suseboot\yaboot.ibm which results
in a file not found error (seen on many openSUSE ppc media).
With this patch the above will evaluate to boot cd:0,\suseboot\yaboot.ibm
and yaboot will load.

This patches copies all needed ppc files to qemu and modifies them.
The generated OpenBIOS image must be loaded at adresse 0xfff00000 by Qemu.
It is able to load Yaboot from disk and Yaboot is able to load Linux, but Linux hangs somewhere... of course it needs more work (but this cleans up my patch queue).
Thank you to Blue Swirl and Aurelien Jarno for their help.
