From: Adrian Bunk <bunk@stusta.de>
SCSI=m must disallow static drivers.
The problem is that all the SATA drivers depend on SCSI_SATA.
With SCSI=m and SCSI_SATA=y this allows the static enabling of the SATA
drivers with unwanted effects, e.g.:
- SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y
-> SCSI_ATA_ADMA is built statically but scsi/built-in.o is not linked
into the kernel
- SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y, SCSI_SATA_AHCI=m
-> SCSI_ATA_ADMA and libata are built statically but
scsi/built-in.o is not linked into the kernel,
SCSI_SATA_AHCI is built modular (unresolved symbols due to missing
libata)
