+Subject: [PATCH] mdraid: fix metadata 1.0 detection in userspace utilities on
+ IEEE1275
+
+The powerpc guard in grub_mdraid_detect skips metadata 1.0 to avoid a
+firmware block issue, but also ends up applying to userspace utilities
+where reads will be going through the kernel. Extend the conditional
+with !defined(GRUB_UTIL) so utilities like grub-install can detect
+metadata 1.0 arrays.

+Subject: [PATCH] grub-install: use search.fs_uuid for RAID1 on IEEE1275
+
+On IEEE1275, grub-install hardcodes an mduuid prefix for RAID
+abstractions, requiring array assembly at boot. This fails on metadata
+1.0 partitions because detection is skipped due to a firmware issue.
+
+Since RAID1 mirrors are individually readable, use search.fs_uuid on
+IEEE1275 to find the boot filesystem on any member partition and avoid
+requiring array assembly.
