is there a value to CONFIG_NO_ATA_LEGACY?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  in drivers/ata/libata-sff.c:

...
#if defined(CONFIG_NO_ATA_LEGACY)
                /* Some platforms with PCI limits cannot address compat
                   port space. In that case we punt if their firmware has
                   left a device in compatibility mode */
                if (legacy_mode) {
                        printk(KERN_ERR "ata: Compatibility mode ATA is not supported on this platform, skipping.\n");
                        return -EOPNOTSUPP;
                }
#endif
...

  there is no Kconfig file that defines that variable -- should that
test be removed?  or is something eventually coming that defines it?
