libata: implement and use ata_port_desc() to report port configuration
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. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
