help with powerpc asm (moving grub_ieee1275_entry_fn initialization to c

For the i386-ieee1275 port, I'd need to move grub_ieee1275_entry_fn
initialization in powerpc from cmain.c to crt0.S, so that code in cmain.c
can be shared with i386.

The problem is I have no clue about powerpc assembler.  On i386, this is
just done with a "movl %eax, EXT_C(grub_ieee1275_entry_fn)" but I don't know
the equivalent.  Furthermore, the code in crt0.S seems to be pushing arguments
(up to 3 according to cmain.c) in a loop, which got me really confused.

Anyone who is familiar with powerpc assembler could have a look?  See attached
