Source: linux Version: 4.4 In Linux v3.19, CONFIG_MAC_SCSI became a tristate option (instead of bool). In Linux v4.4, CONFIG_MAC8390 became a tristate option (it too was previously bool).
Please set CONFIG_MAC_SCSI=m and CONFIG_MAC8390=m for m68k kernel builds to reduce the size of the kernel binary. The former is a SCSI host adapter driver and the latter is an Ethernet NIC driver. Both drivers are only relevant to the Mac sub-architecture and are not used on Amiga, Atari etc. --
