  • Currently, port configuration reporting has the following problems.

    * iomapped address is reported instead of raw address
    * report contains irrelevant fields or lacks necessary fields for
    non-SFF controllers.
    * host->irq/irq2 are there just for reporting and hacky.

    This patch implements and uses ata_port_desc() and
    ata_port_pbar_desc(). ata_port_desc() is almost identical to
    ata_ehi_push_desc() except that it takes @ap instead of @ehi, has no
    locking requirement, can only be used during host initialization and "
    " is used as separator instead of ", ". ata_port_pbar_desc() is a
    helper to ease reporting of a PCI BAR or an offsetted address into it.

    LLD pushes whatever description it wants using the above two
    functions. The accumulated description is printed on host
    registration after "[S/P]ATA max MAX_XFERMODE ".

    SFF init helpers and ata_host_activate() automatically add
    descriptions for addresses and irq respectively, so only LLDs which
    isn't standard SFF need to add custom descriptions. In many cases,
    such controllers need to report different things anyway.

  • It was always set to ata_port_disable(). Removed the hook, and replaced
    the very few ap->ops->port_disable() callsites with direct calls to
    ata_port_disable().

  • * ->irq_ack() is redundant to what the irq handler already
    performs... chk-status + irq-clear. Furthermore, it is only
    called in one place, when screaming-irq-debugging is enabled,
    so we don't want to bother with a hook just for that.

    * ata_dummy_irq_on() is only ever used in drivers that have
    no callpath reaching ->irq_on(). Remove .irq_on hook from
    those drivers, and the now-unused ata_dummy_irq_on()

  • Alan Cox suggested that the solution to the FIXMEs in pata_icside is
    to use a private postreset method to detect the lack of devices on a
    port, and in such a case, disable the interrupt for the port.

    This patch implements such a method, and removes the hard coded
    disable of port 0. Tested as working.
