Feature request to add ppc64el bootloader support via Open Firmware and PReP partitions; no maintainer response or labels after 46 days

Suggested action: needs triage

Reason: The issue has no labels, no maintainer response, no assignee, and zero comments after 46 days. It is a feature request requiring architectural decisions about bootloader support for ppc64el systems. The lack of maintainer engagement indicates it needs triage to determine if this is a priority and whether the proposed approach aligns with the project's roadmap.

Issue body

### Feature Description Add support for installing bootloaders on IBM POWER 64-bit Little Endian (`ppc64el`) systems using Open Firmware (IEEE 1275) and PReP boot partitions. ### Implementation Details 1. **PReP Boot Partition**: - Ensure partition schema includes a dedicated PPC PReP Boot Partition (MBR type `0x41`, GPT GUID `9E364D55-E44C-544E-A938-35AABCF5A403` / `prep` flag, size ~8MB). 2. **Open Firmware ELF Build**: - Build Open Firmware ELF image using `grub-mkimage -d /usr/lib/grub/powerpc-ieee1275 -o /tmp/grub.elf -O powerpc-ieee1275 -p /boot/grub ...`. 3. **Raw DD Installation**: - Write `/tmp/grub.elf` raw into the PReP boot partition node (`dd if=/tmp/grub.elf of=/dev/loopXp<part_num>`).
