If you do "make ARCH=3Dm68k mac_defconfig" resp. "make ARCH=3Dm68k amiga_defconfig", it will expand the reduced defconfi= g. The MAC_PARTITION resp. AMIGA_PARTITION options will be enabled, as they default to y in Kconfig for the Mac resp. Amiga platform. We could also disable PARTITION_ADVANCED, but this would drop support for non-native partition types[*]. As m68k developers/users tend to mov= e disks between systems, it may if more partition support is included in = the defconfigs. [*] Default partition support with PARTITION_ADVANCED=3Dn would be: - Everybody has MSDOS and EFI support, - Amiga has Amiga support, - Atari has Atari suport, - Mac has Mac support. - Sun3/3x has Sun partition support, - VME has SYSV68 partition support. The multi_defconfig would have all of them, but that kernel image may b= e too big to boot on all systems. So please look at at least one of the full expanded .config files, to see if there's more rubbish to disable (or to enable ;-) in the non-platform-specific = options.
