2004-12-04 Marco Gerards <metgerards@student.han.nl>
Modulize the partition map support and add support for the amiga partition map. * commands/ls.c: Include <grub/partition.h> instead of <grub/machine/partition.h>. * kern/disk.c: Likewise. * kern/rescue.c: Likewise. * loader/i386/pc/chainloader.c: Likewise. * normal/cmdline.c: Likewise. * kern/powerpc/ieee1275/init.c: Likewise. (grub_machine_init): Call `grub_pc_partition_map_init', `grub_amiga_partition_map_init' and `grub_apple_partition_map_init'. * conf/i386-pc.rmk (kernel_img_SOURCES): Remove `disk/i386/pc/partition.c'. Add `kern/partition.c'. (kernel_img_HEADERS): Remove `machine/partition.h'. Add `partition.h' and `pc_partition.h'. (grub_setup_SOURCES): Remove `disk/i386/pc/partition.c'. Add `kern/partition.c', `partmap/amiga.c', `partmap/apple.c' and `partmap/pc.c'. (grub_emu_SOURCES): Likewise. (pkgdata_MODULES): Add `amiga.mod', `apple.mod' and `pc.mod'. (amiga_mod_SOURCES, amiga_mod_CFLAGS, apple_mod_SOURCES) (apple_mod_CFLAGS, pc_mod_SOURCES, pc_mod_CFLAGS): New variables. * conf/powerpc-ieee1275.rmk (grub_emu_SOURCES): Remove `disk/powerpc/ieee1275/partition.c'. Add `kern/partition.c', `partmap/amiga.c', `partmap/apple.c' and `partmap/pc.c'. (grubof_SOURCES): Likewise. * disk/i386/pc/partition.c: File removed. * disk/powerpc/ieee1275/partition.c: Likewise. * include/grub/powerpc/ieee1275/partition.h: Likewise. * include/grub/i386/pc/partition.h: Likewise. * kern/partition.c: New file. * partmap/amiga.c: Likewise. * partmap/apple.c: Likewise. * partmap/pc.c: Likewise. * include/grub/partition.h: Likewise.. * include/grub/pc_partition.h: Likewise. * util/grub-emu.c: Include <grub/partition.h> instead of <grub/machine/partition.h>. (main): Call `grub_pc_partition_map_init', `grub_amiga_partition_map_init' and `grub_apple_partition_map_init' and deinitialize afterwards. * util/i386/pc/biosdisk.c: Include `#include <grub/partition.h>' and `include <grub/pc_partition.h>' instead of `<grub/machine/partition.h>'. * util/i386/pc/grub-setup.c: Likewise. * util/i386/pc/biosdisk.c: Likewise. (grub_util_biosdisk_get_grub_dev): Only access the PC specific partition information in case of a PC partition. * util/i386/pc/grub-setup.c: Include `#include <grub/partition.h>' and `include <grub/pc_partition.h>' instead of `<grub/machine/partition.h>'. (setup): Only access the PC specific partition information in case of a PC partition.
