* util/powerpc/ieee1275/grub-mkimage.c: Include <string.h>. (note_path): Remove variable. (GRUB_IEEE1275_NOTE_NAME): New macro. (GRUB_IEEE1275_NOTE_TYPE): Likewise. (grub_ieee1275_note_hdr): New structure. (grub_ieee1275_note_desc): Likewise. (grub_ieee1275_note): Likewise. (load_note): Remove `dir' argument. All callers updated. Remove `note_img' and `path'. Do not load a file from `note_path'. Initialize a struct grub_ieee1275_note and write that to `out'. Use GRUB_IEEE1275_MODULE_BASE instead of MODULE_BASE.
