Indeed bootable CD images are done with GRUB on ppc64el, but it is
currently broken. debian-installer will provide a kernel, a vmlinux and
a file called debian-cd_info.tar.gz containing the grub files. I have
put an example of such a directory tree there:
http://temp.aurel32.net/ppc64el/d-i/
The tarball should be decompressed in the root of the CD-ROM, while the
kernel and initrd should be placed in the /install directory. The ISO
image should be generated with the --chrp-boot argument. Beside that the
default options of genisoimage should be used, there is no need to
specify any strange HFS option like on powerpc (Note: I only tested that
on a VM using SLOF, it will be nice if someone with access to bare metal
can confirm that).
Don't hesitate to ask more details if needed. I will tell you once GRUB
is fixed and all these files are in place on d-i.debian.org.
Thanks,
Aurelien
