    Subject[2.6 patch] SCSI_SATA has to be a tristate
    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)
